Product Description
Magnesium diboride (MgB2) is an ionic compound with a hexagonal crystal structure. It is an intercalation type compound, with magnesium layers and boron layers alternately arranged. Magnesium diboride (MgB2) turns into a superconductor at a temperature slightly close to the absolute temperature of 40K (ie -233 ℃). Its transition temperature is almost twice that of other superconductors of the same type, and its actual working temperature is 20~30K, which is the highest critical temperature of metal compound superconductors at present. As a new material with superconductivity, magnesium diboride opens up a new way for the study of a new generation of high-temperature semiconductors with simple structures. It is characterized by abundant resources, low price, high conductivity, easy synthesis, and simple processing. Since magnesium diboride is easy to be made into thin films and wires, it can be widely used in the manufacture of various electronic instruments such as CT scanners, components of supercomputers, and components of power transmission equipment. It has a wide range of electronics and computer fields. Application prospects.
