Magnesium Boride Powder Description

Magnesium boride powder CAS NO:12007-25-9 is an inexpensive and simple superconductor. Its superconductivity was announced in the journal Nature in March 2001. Its critical temperature (Tc) of 39 K (-234 °C; -389 °F) is the highest amongst conventional superconductors. This material was first synthesized and its structure confirmed in 1953, but its superconducting properties were not discovered until 2001. The discovery caused great excitement. Though generally believed to be a conventional (phonon-mediated) superconductor, it is a rather unusual one. Its electronic structure is such that there exist two types of electrons at the Fermi level with widely differing behaviors, one of them (sigma-bonding) being much more strongly superconducting than the other (pi-bonding). This is at odds with usual theories of phonon-mediated superconductivity which assume that all electrons behave in the same manner. The theoretical understanding of the properties of MgB2 has almost been achieved with two energy gaps. In 2001 it was regarded as behaving more like a low-Tc metallic than a high-Tc cuprate superconductor.

Magnesium Boride Powder Applications

Due to its high hardness, extreme melting point, and chemical inertness, MgB2 is a candidate for a number of applications. Superconductive properties
