Magnesium Diboride Powder: Overview
An inorganic compound having the molecular formula MgB2. It is an insoluble, dark gray solid. It is an hexagonal crystal structure ionic compound. It is an intercalation compounds with alternating layers boron and magnesium. Because of its superconductivity at 39.5 K (-234degC), this compound is interesting. MgB2 has a composition that is significantly different to most low-temperature superconductors based on transition metals.
Although scientists have known magnesium diboride since the 1950s, they have not yet studied its superconductivity. It is the property of this material to conduct electricity flawlessly without resistance when it’s cooled to absolute zero. In January 2001, all this changed. Jun Akimitsu from Tokyo’s Aoyama Gakuin University revealed that he and his group had found that magnesium diboride was superconducting at a temperature of 39 Kelvin (-389 F), which is nearly the same as the current metal. It is twice as hot as the conductor. This news prompted experimenters from all over the world to try and duplicate the Japanese discovery.

What are the possible uses for Magnesium Diboride Powder
Superconducting magnets, power transmission line and sensitive magnetic fields detectors are some of the potential uses for magnesium diboride.
Magnesium Diboride has recently attracted much attention. Research is mainly focused on the properties superconducting and synthetic elements. These include electrical conductivity at ambient temperature, corrosion resistance, fluoride and electrical conductivity. However, there are very few studies.
MgB2 can be sintered and densified more easily than TiB2, and it has an electrical conductivity that meets the requirements of aluminum electrolytic catalysts. MgB2 as well as its composite materials could be widely used for aluminum electrolysis cathodes.
Different from incomplete combustion of elemental bore through a thick glass oxide layer that prevents oxygen diffusion, magnesium diboride burns completely with oxygen or in an oxidant mixture. Magnesium boride has been suggested as a fuel to ramjet engines. MgB2 can also be used in enhanced explosives, propellants, and for similar reasons.
