Chapter 467: High temperature superconducting material

In the celadon science and technology research building, Bi Ye, director of the physics laboratory, and Guo Jianyu, director of the materials and chemistry laboratory, came to the laboratory together.
They looked expectantly, staring at the equipment operated by the researchers in front.
This is the material being processed. If it succeeds, it will almost affect the trend of future porcelain products.
They are now conquering high-temperature superconducting materials, and have now entered the final stage of research.
Bi Ye watched the researchers busy, and said with emotion: "We have searched for many materials, and none of them can raise the superconducting critical temperature to 300k.
Finally, it happened to find the poly-iron-barium alloy material, but it did not expect that its superconducting critical temperature could reach 2273k.
This is an extremely high critical temperature of more than 2000 degrees Celsius. Is a veritable high-temperature superconducting material.
Those superconducting materials that can only reach 100k can only be called low-temperature superconducting materials in the future.
Can no longer be called high-temperature superconducting materials, because they are not worthy. "
Guo Jianrong said nervously: "Polyiron-barium alloy material, it just solves the critical superconducting temperature of superconducting materials.
Its critical magnetic field strength can only reach 0.001T, and other materials can reach 0.08T after processing.
But even with such a high magnetic field strength, we still cannot meet our goals.
100T super strong magnetic field required by the mass accelerator.
In order to generate such a high super strong magnetic field, how can the critical magnetic field of superconducting materials reach 0.1T, which is already the lowest extreme value.
Now it still depends on the post-processing of the polyiron barium alloy material to see if it can reach the ideal state.
I can only hope for post-processing, and now I want to delete other materials. There is not much time left for the start of the Mass Accelerator project, and we do not have enough time. "
Bi Ye also nodded, staring closely at the operation of the scientific researcher.
If the research and development of ordinary superconducting materials, they have already completed.
Now ordinary superconducting materials have been used in various parts of the laboratory.
But this superconducting material is used to make mass accelerator coils.
Must be able to withstand large currents, temperatures and magnetic fields.
Researchers quickly heat-treated the polyiron-barium alloy material, which is already the 14678th heat treatment scheme.
Bi Ye took over the heat-treated superconducting material, and he immediately began testing the superconducting material.
The first thing to check is whether the material has damaged its superconducting properties due to post-processing. Only materials with superconducting properties can enter the next round of testing.
After Bi Ye preliminarily processed the superconducting material, he began to check its superconducting characteristics.
Bi Ye energized the two poles of the superconducting material, and at the same time observed the changes in voltage and current with a detection device.
When the superconducting material is in the superconducting state, the resistance is zero, and it can transmit power without loss.
Ohm's law no longer applies in this state. He must test with more advanced methods.
The most advanced instruments in the laboratory test the resistance of superconducting materials. Sure enough, the resistance has dropped to zero under normal temperature conditions in the laboratory.
It can now be preliminary verified that this post-processed material has superconducting characteristics.
Director Bi Ye was uneasy in agreeing with the results of the experiment. He immediately tested the superconducting properties of the material by other methods.
Bi Ye took out a superconducting ring and placed it in a variable magnetic field.
The superconducting loop was found to induce an induced current in a variable magnetic field, and this current was maintained without attenuation.
When Bi Ye observed that a continuous current was generated in the superconducting loop.
He can initially confirm that this material has superconducting properties.
As long as you go through the final detailed test, it is another feature to verify the superconducting material.
There are two major characteristics of superconducting materials, except that the resistance is zero in the superconducting state.
It is also diamagnetic, and even a strong magnetic field cannot detect it in a superconducting ring.
Bi Ye tried to test the superconducting ring with a super strong magnetic field of up to 10T.
He found that even for this length of time, the superconducting ring could not be detected.
By examining the two characteristics of superconducting materials, he has verified that superconducting materials are stably in a superconducting state.
He placed the material in a high-temperature place of 2273k and tried to see if he could maintain the superconducting state stably at the critical temperature.
Repeating the previous experimental operation, it was found that the superconducting material is still in a superconducting state.
This experiment proves that this heat treatment scheme will not destroy the high-temperature superconducting characteristics of the polyiron-barium alloy material.
Bi Ye uses the smart ring to open the physical calculator.
He calculated the critical magnetic field of superconducting materials, and then arranged corresponding experiments.
The magnetic field strength required to destroy the superconducting state of the superconducting material and change to the normal state is represented by Hc.
The relationship between Hc and temperature T is Hc = H0 [1- (T / Tc) 2], where H0 is the critical magnetic field when 0K.
By simply in this formula, Bi Ye quickly calculated the approximate magnetic field strength of the critical magnetic field of the polyiron-barium alloy superconducting material.
He directly instructed the scientific researchers: "Starting from 0.05T and rising at a rate of 0.01T, verify whether this superconducting material can meet the requirements."
After a simple test, Bi Ye found that this time the material basically met his requirements.
No need for a little bit of rise test, start directly from the minimum magnetic field he calculated.
After he ordered it, he only saw the intelligent robot take the material to a very tightly sealed laboratory.
This is a laboratory that can generate 10T super strong magnetic field. As long as the super strong magnetic field leaks out, it will destroy all personnel and equipment in the laboratory.
The reason why the laboratory can establish a super strong magnetic field of 10T.
The coils and wires of this super strong magnetic field are also made of superconducting materials.
When there was no superconducting material before, I wanted to maintain such a high magnetic field.
Electricity must be provided by a dedicated power plant. It also needs to output huge current.
Now, after using superconducting materials, the energy consumption is less than one ten thousandth of the original.
The experiment is steadily progressing, and soon the superconducting material has reached the last record of 0.08T.
This kind of superconducting material with extremely high critical magnetic field is enough for any other occasion.
But as the magnetic field of the mass accelerator coil ~ EbookFREE.me ~ it still has some shortcomings.
Superconducting materials quickly withstand a super strong magnetic field of 0.08T.
Bi Ye's face showed a surprise. It seems that this experiment should be able to meet their expectations today, and there is great hope to find superconducting materials that meet the requirements.
The experimental data slowly increased, and soon came to the predetermined 0.1T super strong magnetic field.
Superconducting materials in the laboratory are still in a superconducting state.
Guo Jianying shouted in surprise: "We succeeded."
Bi Ye left two lines of tears. He knew what the breakthrough of superconducting materials meant?
He hugged Guo Jianyu in excitement, and murmured in his mouth, "Finally succeeded, we finally made high-temperature superconducting materials."
After Bi Ye reacted, he shouted excitedly: "Quickly, save this processing technology."
