Chapter 2324 This is silicon
In the laboratory, Wang Manshan watched as the two high-frequency induction furnaces were ready, and the two operators next to him were actively debugging!
There are two backup power supplies next to it just in case.
"Old Wang, Yang Bi said, believe in your own feelings!"
"It's nothing to fail, don't have any psychological burden!"
Wang Manshan Zheng pointed, "Uh, understand!"
"Don't worry!"
The last sentence was added, "You talk about the key points, I'm afraid I can't remember it!"
Li Lei didn't mind either and told the meticulous operation process!
"I know, I know!"
Wang Manshan said he remembered it and muttered himself, "Nine hundred degrees, not too high, not too low!"
"Nine hundred degrees, nine hundred degrees!"
Murmuring at Wang Manshan During the operation, the operator received instructions to start the experiment.
First put the treated quartz powder into the crucible of the high-frequency induction furnace, and then add 6 parts of reducing agent.
A piece of bronze is placed in the high-frequency induction furnace on the right.
Everything was ready, Wang Manshan squatted down and waved to Li Lei.
Instantly, the power is turned on.
High-frequency AC power begins to enter the copper tube, and then an induced current appears in the object inside.
Under the operator's control, this induced current quickly enters the copper coil.
The high-frequency induction furnace started to work, and the harsh sound accompanied by heat made Wang Manshan very uncomfortable, but he still looked forward and carefully.
Mr. Peng and Mr. Chen both looked at each other intently. Mr. Ye came to the front and explained to the two.
"This is a high-frequency induction furnace, simply by using the heat it releases, melts itself..."
"It acts directly inside the object."
"This kind of The method can achieve rapid heating. "
"However, safety is a major hidden danger. Safety assessment must be carried out after each use, and demagnetization must be carried out before each use!" "
"Also, the strength of the power supply must be guaranteed..."
Old Ye said from the side, and Mr. Peng and the others listened seriously.
Not only that, others are also focused.
Yang Xiaotao also added from the side, and Han Sanfeng waved to make someone record carefully.
These are not the processes given by the system.
Because the system gives technology with all the preparations, this is a big gap from reality.
What Mr. Ye said is something that can be used in reality.
Or it could be improved in many years, and perhaps better high-frequency induction furnaces will be developed, but now, they can only use these. "It's changing!" Li Hongfeng looked at the bronze in the stove on the right and began to melt, and everyone hurriedly looked at it.
This is the suggestion made by Mr. Ye.
The melting points of some known special metals are used as standards to determine the gear position of the high-frequency induction furnace.
The melting point of bronze is about 800 degrees, which is just right for use.
They had done several experiments in the early stage and could basically determine the frequency required.
This experiment is also for foolproof, otherwise it would be a high-frequency induction furnace.
However, what makes Yang Xiaotao a pity is that he did not find the metal with a melting point of 900 degrees.
Even so, Mr. Peng and Mr. Chen, who were familiar with the situation, nodded with relief.
There are always more solutions than difficulties.
Obviously, Jiubi has used his brains in this regard.
So, after rising to 900 degrees, it depends on Wang Manshan’s golden eyes!
"Team Leader Wang, it's 800 yuan, pay attention!" Li Lei shouted and went straight to the high-frequency induction furnace to get started in person.
Wang Manshan nodded slightly after hearing this!
At this time, Wang Manshan looked at him without blinking, and even if the sweat was flowing down his forehead, he would not dare to touch it with his hands, for fear of missing time!
At the same time, his hand slowly raised and then gently pressed down.
Every time he waved down, Li Lei on the side would increase the frequency a little.
As time passed, the frequency of Wang Manshan's hand waving began to slow down.
The people outside were anxious to see it, but they didn't dare to say anything more, just staring at Wang Manshan's every move inside!
Gradually, it got dark outside.
The lights in the laboratory did not light up.
Just as everyone was waiting anxiously, they suddenly saw Wang Manshan reaching out and pressing down quickly.
Li Lei was shocked, and his hand moved, and the button turned a little more.
The next second, Wang Manshan sat on the ground, wiping the sweat on his face and laughing.
Li Lei quickly recorded the frequency of the current high-frequency induction furnace, and then someone started to flip the boiler inside.
This step, they need to constantly reverse the transfer of it fully reacts with the reducing agent.
At this time, Wang Manshan turned around and waved his hand to the person watching outside, showing a sure smile.
In an instant, people around us hugged each other, followed by cheers, which lasted for a long time!
President Peng and Mr. Chen were also infected. Seeing everyone happy, they applauded involuntarily.
Spang Pa
Applause was given to Wang Manshan, Li Lei and others inside, and also to people outside.
After the applause stopped, Yang Xiaotao quickly reminded everyone, "Please be careful, we are not over yet." "Director Zhu, you must be prepared next." Zhu Ziqing left on the side He came out and shouted loudly, "Please, please don't worry, Yang's army, we are ready long ago."
People from the Institute of Chemistry not far away walked out immediately.
Seeing that everyone was ready, Yang Xiaotao stopped talking and watched the changes in the induction furnace seriously!
According to the process requirements, after continuous flipping and reaction at a high temperature of 900 degrees, crude silicon can be obtained!
The high-frequency induction furnace lasts for more than an hour before the reaction is finished.
After waiting for more than an hour, Li Lei took out the cooling boiler according to the process requirements and quickly cooled it.
Yang Xiaotao quickly moved forward, looking at the gray crystal inside, and a look of relief appeared on his face.
This form has shown that at least half of the success! The next operation falls into the category of chemical reactions!
Yang Xiaotao looked at Zhu Ziqing, "Let's see you next!"
Zhu Ziqing nodded, "I understand!"
After saying that, Zhu Ziqing took people to start wearing it. Protective clothing, gloves, goggles, the whole person is wrapped tightly!
Although it was cold outside, the temperature in the laboratory was not low. If you were in such a body, you would probably sweat all over.
Zhu Ziqing looked at the people behind him, nodded, and then led the group into the laboratory.
Calculate the instruments and equipment inside, and after inspection, start to arrange tasks!
According to the process requirements, everyone put the obtained crude silicon into the reaction kettle again.
Then 6 parts of the reactant were injected...
President Peng and Mr. Wang were watching, and Yang Xiaotao chatted with Mr. Ye for a while before he came to the front.
"Mr. Peng, the leader, the next reaction will take a lot of time. Why don't we go to have a meal first?"
President Peng shook his head, "I'm not hungry, you can go and eat when you are hungry!"
< br>No mistakes, one song, one content, one in 6, one book, one bar, one reading!
Yang Xiaotao looked at Mr. Chen again, and Mr. Chen shook his head.
Now they have no intention of having a meal!
These two people don’t eat them anymore, so no one else dares to eat them.
So everyone continued to wait outside.
This wait was straight to dawn the next day.
When it was dawn outside, Yang Xiaotao heard something behind him. When he looked back, Mr. Peng had already moved his hands and feet and walked towards him!
Not many people were present, after all, they still needed work.
Besides, Old Ye is old and can’t hold on, so he lets him go back to the office to rest!
The rest are Yang Xiaotao, Li Hongfeng, General Peng and Lao Lao, and the guards in charge of security around them.
Seeing that Mr. Chen was still resting on the side, Yang Xiaotao said to the guard on duty not far away, "Let the kitchen arrange food. More!"
The guard nodded and left gently.
President Peng came to Yang Xiaotao, looked at the busy scene inside, and then asked, "How long has it been?"
Yang Xiaotao looked at his watch and said, "It's been eight hours!"
"How is the situation?"
Yang Xiaotao rubbed his face and nodded, "It's going well!"
< br>After all, this is also the first live experiment.
The system only has one process operation diagram in the process, and the specific situation must be based on actual conditions.
Mr. Peng nodded, but his eyes were staring at the lab in the room.
In this environment, persisting for such a long time not only requires physical support, but also firm will!
Yang Xiaotao took out the cigarette box and found that there was only one left in it. He then put it back in his pocket.
"I didn't expect it to take so long!"
"Reaction is so cumbersome!"
Mr. Peng stood with his hands behind his back, "This is what we said. The knowledge on paper is shallow. You must practice it yourself!"
"If you don't do it, you will never know where the gap is!"
Yang Xiaotao nodded slightly.
It’s still not enough preparation!
When the reaction is first started, the amount of reaction reagents required is too small, resulting in incomplete reaction.
When the second step was to collect the gas, I found that the color inside was not right, and more quartz powder was retained in the reactor.
Obviously, the experimental response is not thorough, which will affect the experimental results.
So everyone looked for the reason, and later found that it was not the fault of the process requirements, but the insufficient purity of the reaction reagent and insufficient addition amount.
After reconversion, the experiment was conducted again and finally obtained silicon tetrachloride gas.
Then the operation is now carried out. After heating the hydrogen into the reactor at high temperature, it can fully react to produce high-purity pure silicon and hydrogen chloride gas.
In fact, these simple steps are all explored step by step!
The experiment was able to proceed smoothly, and this is all due to Zhu Ziqing, the professor of chemistry! "Is this going to end?" Mr. Peng watched the people inside come together, as if observing something.
Yang Xiaotao came to his senses and hurriedly looked at it. He saw Zhu Ziqing suddenly raised his head and waved to Yang Xiaotao.
"Success?"
Li Hongfeng also ran over when he heard the movement, and was very curious.
Old Chen also stood up not far away. "I don't know, let's talk about it." Yang Xiaotao stared inside and soon saw Zhu Ziqing walking out holding a reaction dish.
The four of them were busy waiting. "Yang Bu, see if this is high-purity silicon." Zhu Ziqing walked to Yang Xiaotao, his voice was exhausted.
The researchers behind them walked out and helped each other take off their protective suits, revealing their sweaty figures.
The four people at this moment were setting their eyes in the small reaction dish.
A small pile of blue-gray crystals.
It looks a bit like crystal, but it's very small.
Even when the sun shines in, there is a metallic color.
Yang Xiaotao carefully took the reaction dish and his breathing became lighter, as if he was afraid that he would blow away with force.
"Is this, silicon?"
Mr. Peng asked in a low voice.
Old Chen rubbed his eyes and looked carefully, trying to see what was different from what he imagined.
Li Hongfeng didn't know what this was at all, but all three of them looked at it, and he also came over to look at it.
Yang Xiaotao compared the information introduced in the ultra-pure silicon production process, and then nodded vigorously, "Yes, this is silicon!"
"A thing that can bring about changes in the world .”
After hearing this, Mr. Peng and the other two looked at each other.
If it weren't for their own eyes, this thing was extracted from the stone, which would be incredible.
