Magnesium diboride is an ionic compound with a hexagonal crystal structure.
It’s a brittle, hard, malleable substance, and it’s an intercalated compound,
The magnesium and boron layers are arranged alternately at temperatures slightly closer to the absolute temperature of 40K (i.e. -233℃).
It turns into a superconductor. Its transition temperature is almost twice as high as that of other superconductors of the same type,
And its actual operating temperature is 20~30K. Magnesium diboride (MgB2), its superconducting transformation
The temperature is 39K, or minus 234℃, which is currently the highest metal compound superconductor
Critical temperature. As a new material with superconductivity, magnesium diboride is a new generation
High temperature semiconductor with simple structure has opened a new way. Superconducting material magnesium diboride is
A metal compound of magnesium and boron bound in a ratio of 1:2. It is characterized by abundant resources,
Low price, high conductivity, easy synthesis, simple processing. Because magnesium diboride is easy to make
Film and wire, widely used in the manufacture of CT scanners and other electronic instruments,
Components for manufacturing supercomputers and power transmission equipment. In the field of electronics
And the computer field has a broad application prospect. China adopts high temperature and high pressure method, short time
A high density magnesium diboride superconductor sample has been successfully synthesized, which is close to the international level.
Potential applications of MGB2 include superconducting magnets, power transmission lines and sensitive magnetic field detectors.
