Special conductive materialsIt is an important foundational material used for manufacturing superconductors, with excellent electrical properties and significant applications in fields such as electronics, power, and information. With the continuous deepening of research on superconductivity in China and the country's emphasis on technological innovation, more and more enterprises are beginning to develop and produce related products.

Below, the editor will introduce the classification of special conductive materials.

1. High temperature superconducting tape: It is formed by using special processes to make strip structures of base metals such as copper or aluminum, stretching and forming them, and then annealing them. Its characteristics are: volume resistivity close to zero, Curie temperature above 4T, critical current density up to 10-9Cscm2, loss tangent at room temperature of 0.0005%, which is expected to achieve operation at room temperature; Due to its high-temperature properties and low losses, it has broad application prospects in many fields.

2. Low temperature superconductor: refers to substances in liquid hydrogen (H2), such as mercury amalgam lithium-ion batteries, sodium sulfur batteries, cadmium batteries, zinc manganese oxide dry electrodes, and so on. When the resistivity of these substances is low to a certain extent, they can remain stable in liquid nitrogen and are called low-temperature superconductors.

3. Iron based high-temperature superconducting wire: Using iron as the matrix, high concentration impurities are formed through doping, and then produced by high-temperature melting method. The characteristics of this material will undergo some changes compared to low-temperature superconductors.

4. Copper oxide: It is a new type of high-temperature insulator. It is composed of copper compounds, which contain various types of impurities. Its coefficient of thermal expansion is very small, so it can be made into various shapes. For example, it can be made in the form of rods, discs, plates, rings, or tubes.

5. Amorphous alloys: including amorphous silicon, amorphous selenium, diamond, etc., all of which are crystals determined by atomic arrangement.

6. Carbon nanotubes: Carbon nanotubes are hollow spherical carbon molecules with a diameter of approximately 0.1-1nm and a wall thickness of approximately 0.5-3nm. It is currently the smallest solid particle discovered and also the weakest known solid internal molecule.

Special conductive materialsIt is a conductive material with special properties, usually made of high-tech materials such as metals, carbon fibers, polymer materials, etc., with specific structures and properties such as high conductivity, anti-static, heat resistance, etc. These special properties make special conductive materials an indispensable part of modern electronic devices and industrial production.

The application of special conductive materials is very extensive, mainly used in fields such as electronic equipment, instruments and meters, and national defense industry. For example, in electronic devices, special conductive materials can be used to make electrodes, conductors, insulators, etc; In instruments and meters, special conductive materials can be used to make sensors, amplifiers, etc; In the defense industry, special conductive materials can be used to make antennas, filters, batteries, and so on.

The characteristics of special conductive materials are very obvious, mainly manifested in the following aspects:

High conductivity: Special conductive materials have extremely high conductivity, which can reach one ten thousandth or even higher.

Anti static function: Special conductive materials have anti-static function and can be used to make anti-static flooring, electrostatic generators, etc.

Good heat resistance: Special conductive materials have high heat resistance and can be used in high-temperature environments.
