Chapter 188 Room Temperature Superconducting Materials
When Zhou Yu walked to the superconducting laboratory, he recalled the content of superconducting technology in his mind.

The DC resistivity of the conductor suddenly disappears under certain conditions, which is called the zero resistance effect. The conductor that reaches this state is called the superconducting state, and the moment when it does not enter the superconducting state is called the ground state.

The conductor has no resistance, and no heat loss occurs when the current flows through the superconductor.

There is no resistance in the conductor, so no voltage will be generated, and the superconducting current in the superconductor has the characteristic of zero voltage.

The current in a superconductor can form a strong current in the wire without resistance, thereby generating a super-strong magnetic field.

When the conductor is in the superconducting state, the magnetic induction in the superconductor is zero, which will push out the magnetic field that originally existed in the body.

The judgment of a superconductor is confirmed by the two phenomena of zero resistance effect and zero magnetic induction.

If these two phenomena occur in a certain conductor, it can be confirmed as a superconductor.

Zhou Yu continued to recall the principle of superconductor production.

In superconducting metals, electrons attract each other through lattice waves to form electron pairs.

Numerous electron pairs overlap each other and often exchange objects to form a whole. The flow of electron pairs as a whole produces superconducting current.

Since a certain amount of energy is required to disassemble electron pairs, there is an energy difference between the ground state and the superconducting state in a superconductor, that is, an energy gap.

Different materials have different energy gaps, and the conditions under which they form superconductors are also different.

Now it is found that the only materials that form superconductors are metals, and people can only try to find high-temperature superconductors by making different alloys.

The approach of Ma Shangshu and Feng Yunde is to discover a new type of material that can produce superconducting phenomena, and to test the conditions for its superconducting state to be achieved.

Zhou Yu walked into the superconducting laboratory and saw that the people here were busy. He did not interfere with the work of the researchers and walked towards the direction with the most people.

He found that these people were surrounding several blue-green plates. Some plates had silver-white metal balls suspended above them, and some plates contained silver-white metal balls.

The plate is covered with a glass cover that shows the temperature inside the plate.

Zhou Yu immediately understood that the plate was made of superconducting material. The superconducting material entered the superconducting state, and the electromagnetic induction intensity was zero, resulting in the phenomenon of repelling magnetic induction lines.

The magnetic metal sphere is directly repelled by a plate of superconducting material, above which it is suspended.

The temperature at which the plate is located is the temperature required for the superconducting state of this superconducting material.

Zhou Yu watched the temperature of the plate with metal balls suspended above.

As long as the temperature of the plate is below 55 degrees Celsius, there will be metal balls suspended above it.

When Zhou Yu saw this, he immediately understood that Ma Shangshu had successfully researched room temperature superconducting materials.

The upper limit of the minimum temperature of this normal-temperature superconducting material is so high that it reaches an astonishing 55 degrees above zero.

This is a veritable room temperature superconducting material.

Ma Shangshu and Feng Yunde walked over, and they immediately spotted Zhou Yu in the crowd.

Seeing them coming, Zhou Yu smiled and said happily: "Congratulations on your successful development of room temperature superconducting materials. The neutrino communication base station is in big trouble. Fortunately, your project is successful and their problems are solved."

Ma Shangshu said modestly: "I didn't do anything to discover the room temperature superconducting material. I just tested the superconducting properties of this material."

Feng Yunde also grinned and said: "This material is just one of the silicon-based polymer materials I have developed. If Ma Shangshu hadn't discovered that it has superconducting properties, it might have been buried in our laboratory."

"Don't be modest, both of you, you have made great contributions." Zhou Yu smiled.

"What are the physical properties of this superconducting material? Can it be used to make wires? Its production process is not complicated, and what is the output?"

Zhou Yu asked with concern that if this kind of superconducting material can be used in industry, it must meet the corresponding standards. The output of this kind of superconducting material should not be too low, and the manufacturing process should not be too troublesome.

Feng Yunde took a plate from the booth, put it in his hand to display, and introduced: "This superconducting material is a silicon-based polymer. I just imitated the principle of organic materials and replaced carbon chains with silicon chains.

I have produced the basic raw material 'silicene' of the silicon chain in the laboratory. Its structure is very similar to that of ethylene, but the carbon atoms are replaced by silicon atoms.

With silicene as a material, I made a lot of silicon-based polymer materials.

This superconducting material is to replace the hydrogen atom on the third silicon atom of tetrasilene with a divalent iron atom.

The polybutasilene isoferron is used as a raw material to carry out a polymerization reaction, and the polybutasilene isoferron is the superconducting material.

I named this superconducting material green ferrosilicon.

Its reaction conditions are not difficult, and the equipment used is also the polymerization reaction of organic materials, but the catalyst and reaction conditions are different. "

"The research and development process of green ferrosilicon is quite complicated, and this silicon-based organic-like material should be the focus of the materials laboratory in the future.

The treasure mine of organic materials has not been dug up to now, and you have developed a new category of materials. You must not waste this opportunity. "Zhou Yu said happily.

The materials laboratory led by Feng Yunde has developed a new type of material, and its potential is not inferior to that of organic materials and nanomaterials.

"Mr. Zhou, every scientist in our Materials Research Institute can see the potential of silicon-based polymer materials." Feng Yunde said confidently.

Ma Shangshu interjected from the side: "The topic has gone so far, let me introduce the physical properties of green ferrosilicon."

After Ma Shangshu's introduction, Zhou Yu understood some characteristics of green ferrosilicon.

Green silicon ferrosilicon has good toughness, but its hardness is not high, and its hardness is similar to that of metallic silver.

However, ferrosilicon chloride has good chemical properties and is very light in weight.

As a conductor, green ferrosilicon can be mixed with other organic materials and braided into cables for long-distance power transmission.

Zhou Yu learned that green ferrosilicon can be used to make cables, and he told Feng Yunde: "You make a batch of green ferrosilicon and send it to the neutrino communication laboratory, and ask Zhao Zhao to use green ferrosilicon to improve the neutrino communication base station. "

Feng Yunde waved his hand and said: "The production of such a simple material does not require the equipment in our laboratory at all.

Besides, the output of equipment in the laboratory is very low, and it takes several months to produce 100 kilometers of green ferrosilicon.

Its preparation process is really not difficult, and Xinghuo Materials can make green ferrosilicon.

We have already registered a patent for this material in China, and we are not afraid of it leaking secrets. "

After Feng Yunde finished speaking, he flattered and said: "Mr. Zhou still has the foresight to establish a technology research and development center in Xiong'an New District.

Many technology companies have applied the artificial intelligence Mozi, and the products are emerging one after another, and the speed of patent applications has already caused people to complain.

The slow-working people in the National Patent Office will change their work style and use artificial intelligence technology to improve the patent approval time. "

"It's not my credit, it's social changes affecting government work." Zhou Yu said modestly.

After learning about the situation of green ferrosilicon, he immediately notified Gou Fugui, the general manager of Xinghuo Material Company, and asked him to contact Feng Yunde, director of the Materials Research Institute.

Large-scale production of green ferrosilicon, a superconducting material that can be used to make cables, is not only used by neutrino communication base stations, but China's main power grid is a major consumer of this material.
