Chapter 58 Room Temperature Superconductors

Hear Huang Haojie's order.

Fang Ping nodded and left the new material laboratory.

The reason why Huang Haojie didn't want to get entangled with the villagers was mainly because if this continued, it would be of no benefit to both parties, and once it was hyped up, it would be a troublesome matter.

After all, cyber violence is difficult to explain clearly. People will subconsciously sympathize with the weak, because most people are from the middle and lower classes, and their hatred of the rich is subconscious.

Instead of wasting time entangled with the villagers, it is better to find a new place. Anyway, there are many places suitable for building wind power stations in coastal areas, so why bother to seek swords there.

After Fang Ping left, Huang Haojie continued to return to the laboratory, where he was researching iron-silver superconducting alloys.

In fact, iron-based superconductors were developed by Sunlanders in 2008, and then a series of iron-based superconductors were developed, which are mainly divided into four categories.

Before iron-based superconductors came copper-based superconductors. In 1986, scientists discovered the first high-temperature superconducting material—lanthanum barium copper oxide.Since then, copper-based superconducting materials have become a research hotspot for physicists all over the world.

However, until today, the physics community has not yet reached a consensus on the high-temperature superconducting mechanism of copper-based superconducting materials, which also makes high-temperature superconductivity one of the biggest mysteries in condensed matter physics today.

Therefore, many scientists hope to find new high-temperature superconducting materials other than copper-based superconducting materials, so as to make the mechanism of high-temperature superconducting clearer.

Just in February 2008, Sunland scientists first reported that the fluorine-doped lanthanum oxide iron arsenic compound has superconducting properties at a critical temperature of 2 Kelvin (minus 26°C).

On March 3, a research team led by Chen Xianhui of Dongtang University of Science and Technology reported that the fluorine-doped samarium oxide iron arsenic compound also becomes a superconductor at a critical temperature of 25 Kelvin (minus 43°C).

On March 3, a research team led by Zhao Zhongxian from the Institute of Physics of Dongtang Academy of Sciences reported that the high-temperature superconducting critical temperature of fluorine-doped praseodymium-oxygen-iron-arsenic compounds can reach 28 Kelvin (minus 52°C).

On April 4, the research team made a new discovery: If the fluorine-doped samarium oxide iron arsenic compound works under pressure, its superconducting critical temperature can be further raised to 13 Kelvin (minus 55°C).

In addition, the scientific research team led by Wen Haihu from the Institute of Physics of the East Tang Academy of Sciences also reported that the superconducting critical temperature of strontium-doped lanthanum-iron-arsenic compounds is 25 Kelvin (minus 248.15°C).

Iron-based superconductor is a superconducting material based on iron-containing compounds, and its superconductivity is mainly dominated by 3d orbital electrons in iron.

It can have high-temperature superconductivity above 40 Kelvin, and superconductivity occurs on the iron-arsenic (or iron-selenium) plane of the quasi-two-dimensional crystal structure. The study of it will help reveal the mechanism of high-temperature superconductivity.

Of course, both copper-based superconductors and iron-based superconductors have weaknesses that are difficult to overcome.

High cost is one thing, after all, problems that can be solved with money are not problems.

But these superconductors have a fatal weakness, that is, to maintain the superconducting state, they must be in a low temperature state.

What we often hear about low-temperature superconductors and high-temperature superconductors is actually a relative concept.

High-temperature superconductors are a family of superconducting substances with general structural features and relatively moderately spaced cuprate planes, they are also called cuprate superconductors.

High-temperature superconductors are not hundreds of thousands of high temperatures as most people think, but are much higher than the ultra-low temperatures required for superconductivity, but they are also about minus 200 degrees Celsius.

In the superconductivity studied by human beings, the temperature has been increased a lot, so it is called a high-temperature superconductor.

But even for so-called high-temperature superconductors, to maintain a superconducting state, liquid nitrogen must be used for continuous cooling. Not only is the maintenance cost very high, but the process is also very complicated.

Therefore, the concept of room temperature superconductor came into being. Room temperature superconductor is also called room temperature superconductor, which is a material that can exhibit a superconducting state without low temperature.

Like the planet Pandora in the movie "Avatar", those lands floating in mid-air contain huge superconducting ore.

He had obtained the "Iron-Silver Superconducting Alloy Technology" in parallel time and space before, but the completeness of this document was only about 40% at that time.

After more than a year of accumulation, he raised the integrity of "Iron-Silver Superconducting Alloy Technology" to about 87% from the memory fragments in parallel time and space.

Although the completeness of "Iron-Silver Superconducting Alloy Technology" has been perfected to 87%, he has a feeling that he has no way to start looking at this document.

Because the manufacture of iron-silver superconducting alloys requires three conditions, that is, a large X-ray laser and low temperature and high pressure.

According to the technical design, the power of large-scale X-ray lasers needs to reach 100 million kilowatts, which is the minimum standard. If you want to achieve mass production, the power should reach 500 million kilowatts to start.

Seeing this is simply cheating. What is the concept of 100 million kilowatts? It is equivalent to consuming 100 million kWh of electricity in one hour, 2400 million kWh of electricity a day, and 87 billion kWh of electricity a year.

This is still at the laboratory level. If large-scale production is to be realized, the laser power must be increased to 500 million kilowatts, which is the starting position.

Think about the consumption of 500 million kilowatt-hours of electricity in one hour, and 438 billion kilowatt-hours of electricity in a year.

And consume a huge amount of energy, how much iron-silver superconducting alloy can be produced? About 400 tons.

On average, one ton consumes more than 1 million kilowatt-hours of electricity. This is not counting other costs. In addition to other costs, the cost of a ton of iron-silver superconducting alloy is no less than 5000 million Wah, and one kilogram costs more than 5 Wah.

What's even more deceitful is the 500 million-kilowatt X-ray laser. The cost of this thing is no less than 60 billion Chinese yuan. Including other supporting facilities, the total cost is initially estimated to be about 100 billion Chinese yuan.

If it is really going to be mass-produced, the annual electricity bill will be about 130 billion Chinese yuan.

In addition, the silver content of the iron-silver superconducting alloy itself is about 21%.

At present, the price of industrial silver is about 4.2 Chinese yuan per gram, and one kilogram is about 4200 Chinese yuan. 400 tons of iron-silver superconducting alloy, according to the silver content of 21%, need to use 84 tons of silver, a total of about 3.5 million yuan.

If it is produced on a large scale, for example, it will drive up the price of industrial silver, so the production cost of iron-silver superconducting alloy will be forced to increase.

A room-temperature superconductor worth 5 Huayuan per kilogram can only be used in research such as high-end products or laboratories.

For example, nuclear fusion and superconductor chips. As for superconductor power transmission, don’t even think about it. Even Meilijian’s normal-temperature superconductor power transmission will go bankrupt.

Think about the cost of 5 Huayuan per kilogram. How much does it cost per kilometer to make power transmission cables? One meter of high-voltage wire is about 10 kilograms, and one kilometer is about 10 tons.

A single kilometer of high-voltage wires costs 5 million Chinese yuan, and how many kilometers are needed across the country? The price is simply too touching, and even the five hooligans can't afford it, let alone those weak chickens.

However, even if the cost is high, Huang Haojie still decided to launch this super project. After all, lighting up room temperature superconductors is related to superconductor chips and nuclear fusion.

If nuclear fusion can be identified, then the cost of power generation will drop to a few tenths of the current level. The reduction in power generation cost means that the production cost of room temperature superconductors will decrease, and a virtuous circle will be formed.

Of course, room-temperature superconductors are just one of the conditions for nuclear fusion, and Huang Haojie didn't think he could make them in a short time.

But the iron-silver superconducting alloy must be developed.

　happy mid-Autumn Festival!
