Chapter 467 High-Temperature Superconducting Materials

In the Celadon Science and Technology Research Building, Bi Ye, director of the Physics Laboratory, and Guo Jianhao, director of the Materials and Chemistry Laboratory, came to the laboratory together.

They stared expectantly, staring at the equipment operated by the scientists in front of them.

This is the material being processed. If it is successful, it will almost affect the direction of Qingci technology products in the future.

They are now working on high-temperature superconducting materials and are now in the final stages of tackling key problems.

Bi Ye watched the researchers busy, and he said with emotion: "We have found many materials, but none of them can raise the critical temperature of superconductivity to 300K.

In the end, I coincidentally found a barium iron alloy material, but I didn't expect its superconducting critical temperature to reach 2273K.

This is an ultra-high critical temperature of more than 2,000 degrees Celsius. It 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.

They can no longer be called high-temperature superconducting materials, because they are not worthy. ”

Guo Jianmiao said a little nervously: "Polyiron-barium alloy material, it only 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 treatment.

But even with such a high magnetic field strength, it still can't meet our goal.

The 100T ultra-strong magnetic field required by the mass accelerator.

In order to generate such a high super-strong magnetic field, the critical magnetic field of superconducting materials must reach 0.1T, which is already the lowest extreme value.

Now it is still necessary to look at the post-processing of the barium iron alloy material to see if it can achieve the ideal state.

I can only hope for post-processing, and now I want to delete other materials. Time is running out before the start of the mass accelerator project, and we don't have enough time. ”

Bi Ye also nodded, staring at the operation of the scientific researchers with his eyes.

If they had developed ordinary superconducting materials, they would have already done it.

Ordinary superconducting materials are now used in laboratories.

But this superconducting material is used to make mass accelerator coils.

It must be able to withstand ultra-large current, ultra-high temperature, and ultra-strong magnetic field.

Researchers quickly completed the heat treatment of the barium iron alloy material, which is already the 14,678th heat treatment scheme.

Bi Ye took over the heat-treated superconducting material, and he immediately began to test the superconducting material.

The first step is to detect whether the material has damaged its superconductivity properties due to post-processing. Only materials with superconducting properties are likely to proceed to the next round of testing.

After Bi Ye carried out the preliminary processing of the superconducting material, he began to look at its superconducting properties.

Bi Ye energizes the two poles of the superconducting material, and at the same time observes the change of voltage and current with a detection device.

When the superconducting material is in a superconducting state, the resistance is zero, and it is able to transmit electrical energy without loss.

In this state, Ohm's law no longer applies. He had to use more advanced means to detect it.

The state-of-the-art instruments in the laboratory test the resistance of superconducting materials, and sure enough, the resistance has been reduced to zero at room temperature in the laboratory.

It can now be preliminarily verified that the material that has undergone post-processing this time has superconducting characteristics.

Director Bi Ye was not at ease to agree to the results of the experiment, and he immediately used other methods to test the superconducting properties of the material.

Bi Ye took out another superconducting ring and placed it in a variable magnetic field.

It was discovered that the superconducting ring induces an induced current in a variable magnetic field, which is maintained without attenuation.

When Bi Ye observed, a continuous current was generated in the superconducting ring.

He was able to preliminarily confirm that the material has superconducting properties.

The final step of detailed testing is to verify another property of the superconducting material.

Superconducting materials have two major characteristics, except that the resistance is zero in the superconducting state.

It is also diamagnetic, and even the strongest magnetic field cannot detect in the superconducting ring.

Bi Ye tested the superconducting ring through a super magnetic field of up to 10T.

He found that even the duration of this intensity could not detect the superconducting ring.

Through the test method of two properties of superconducting materials, he has verified that superconducting materials are stably in the superconducting state.

He also placed the material at a high temperature of 2273K to test whether he could stably maintain superconductivity at a critical temperature.

Repeating the experimental operation just now, it was found that the superconducting material was still in a superconducting state.

This experiment proves that the heat treatment scheme does not destroy the high-temperature superconductivity of the barium iron alloy material.

Bi Ye used the smart ring to open the physics calculator.

He calculates the critical magnetic field of superconducting materials and then arranges the corresponding experiments.

The strength of the magnetic field required to destroy the superconducting state of a superconducting material and transform it into a normal state, expressed in Hc.

The relationship between Hc and temperature T is Hc=H0[1-(T/Tc)2], where H0 is the critical magnetic field at 0K.

Through this simple formula, Bi Ye quickly calculated the approximate magnetic field strength of the critical magnetic field of the superconducting material of barium iron alloy.

He directly instructed the researchers: "Starting from 0.05T, the law of 0.01T rises to verify whether this superconducting material can meet the requirements." ”

Through a simple test, Bi Ye found that the materials this time basically met his requirements.

There is no need for a little bit of an ascent test, but a test starts directly from the lowest magnetic field he calculated.

After he finished speaking, he only saw the intelligent robot take the materials to a very tightly sealed laboratory.

This is a laboratory that can generate a 10T super magnetic field, as long as the super strong magnetic field leaks out, it will destroy all the personnel and equipment in the laboratory.

The reason why the laboratory can establish a super strong magnetic field of 10T.

It is the coil and wire of this super magnetic field that are also made of superconducting materials.

In the past, when there were no superconducting materials, it was necessary to maintain such a high magnetic field.

It was necessary to use a special power plant to provide electricity. It also needs to output a huge amount of current.

However, with the use of superconducting materials, the energy consumption is less than 1/10,000 of the original.

Experiments are progressing steadily, and soon the superconducting material has reached the highest record of 0.08T in the last test.

This superconducting material, which has an extremely high critical magnetic field, is sufficient for use in any other context.

But as the magnetic field of the mass accelerator coil, it leaves something to be desired.

The superconducting material quickly withstands a super-strong magnetic field of 0.08T.

Bi Ye showed surprise on his face, it seems that today's experiment should meet their expectations, and there is a great hope to find superconducting materials that meet the requirements.

The experimental data slowly increased, and soon came to the predetermined ultra-strong magnetic field of 0.1T.

Superconducting materials in the laboratory are still in a superconducting state.

Guo Jianmiao shouted in surprise: "We succeeded. ”

Bi Ye left two lines of tears, he knew what the breakthrough of superconducting materials meant?

He hugged Guo Jianmiao excitedly, and muttered: "Finally succeeded, we finally made high-temperature superconducting materials." ”

After Bi Ye reacted, he shouted excitedly: "Quick, quickly save this processing technique." ”
