Overview of magnesium diboride MgB2 powder:

Magnesium diboride is an inorganic compound with the molecular formula MgB2. It is a dark gray insoluble solid. It is an ionic compound with a hexagonal crystal structure. It is an intercalation compound with alternating layers of magnesium and boron. This compound is of interest because of its superconductivity at 39 K (-234°C). In terms of composition, MgB2 is significantly different from most transition metal-based low-temperature superconductors.

Scientists have known magnesium diboride for nearly 50 years, but no one has studied the superconductivity of this material—whether it can conduct electricity perfectly without resistance when it is cooled to a temperature close to absolute zero. All this changed in January 2001. Jun Akimitsu of Tokyo's Aoyama Gakuin University announced that he and his team had discovered that magnesium diboride became superconducting at 39 degrees Kelvin (-389 degrees Fahrenheit), which is almost the current metal. Twice the temperature of the conductor. This news made experimenters all over the world scramble to replicate and confirm the Japanese discovery.

Magnesium diboride transforms into a superconductor at a temperature slightly close to the absolute temperature of 40K (-233°C). Its transition temperature is almost twice that of other superconductors of its kind, and its actual working temperature is between 20-30K. This temperature can be achieved by liquid neon gas, liquid hydrogen or a closed-cycle refrigerator. These methods are simpler and cheaper than the industry's use of liquid helium to cool niobium alloys (4K). Once doped with carbon or other impurities, magnesium boride maintains superconductivity as good as niobium in the presence of a magnetic field or current, or even better.

Magnesium Diboride MgB2 powder Application:

What is the scope of application of magnesium diboride MgB2 powder?

Potential applications of magnesium diboride include superconducting magnets, power transmission lines, and sensitive magnetic field detectors.

Magnesium diboride is a new material that has attracted attention. The research mainly focuses on the properties of synthetic and superconducting elements, used in industrial synthesis and sintering properties, electrical conductivity at room temperature, corrosion resistance of liquid aluminum, and corrosion resistance of fluoride There are few studies, so MgB2 and its composite materials have not been used to cover the cathode area of aluminum electrolysis.

MgB2 is easier to sinter and densify than TiB2, and its electrical conductivity basically meets the requirements of aluminum electrolytic cathodes. Therefore, MgB2 and its composite materials may be widely used as cathode materials for aluminum electrolysis.

Propellants, explosives, pyrotechnics: different from the incomplete combustion of elemental boron through a glass oxide layer that prevents the diffusion of oxygen, magnesium diboride burns completely in oxygen or an oxidant mixture. Therefore, magnesium boride has been proposed as a fuel for ramjet engines. In addition, for the same reason, it has been proposed to use MgB2 in enhanced explosives and propellants.
