Magnesium diboride (MgB?6?0) is an ionic compound with a hexagonal crystal structure. It is a brittle and hard substance with poor ductility. It is an intercalation compound.
The magnesium layer and the boron layer are arranged alternately, and will transform into a superconductor at a temperature slightly close to the absolute temperature of 40K (ie -233°C). Its transition temperature is almost twice that of other superconductors of the same type, and its actual working temperature is 20^30K. Magnesium diboride (MgB2) has a superconducting transition temperature of 39K, or minus 234°C, which is currently the highest critical temperature of metal compound superconductors. 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. The superconducting material magnesium diboride is a metal compound formed by combining magnesium and boron in a ratio of 1:2. It is characterized by abundant resources, low price, high conductivity, easy synthesis and simple processing. Since magnesium diboride is easily made into films and wires, it can be widely used in the manufacture of CT scanners and other electronic instruments.
Manufacture of components for supercomputers and components for power transmission equipment. It has broad application prospects in the electronic field and computer field. my country has successfully synthesized a high-density magnesium diboride superconductor sample using high-temperature and high-pressure methods in a short time, which is close to the international level. Potential applications of magnesium diboride include superconducting magnets, power transmission lines, and sensitive magnetic field detectors.
Researchers discovered in 2001 that a seemingly inconspicuous compound magnesium diboride (magnesium diboride) turns into a superconductor at a temperature slightly close to the absolute temperature of 40K (ie -233°C). Its transition temperature is almost twice that of other superconductors of the same type, and its actual working temperature is 20^30K. To reach this temperature, liquid neon, liquid hydrogen or closed-cycle refrigerators can be used to complete the cooling. These methods are simpler and cheaper than the industrial cooling of niobium alloys (4K) with liquid helium. -Once doped with carbon or other impurities, magnesium boride maintains superconductivity in the presence of a magnetic field or electric current, and its ability to maintain superconductivity is no less than that of niobium alloys, or even better. Its potential applications include superconducting magnets, power transmission lines and sensitive magnetic field detectors
