Lanthanum Hexaboride Part Description

Lanthanum Hexaboride Cathode(LaB6 cathode, also called lanthanum boride cathodeand LaB6 cathode) is an inorganic chemical. With a melting point 2528 K, LaB6 cathode is a refractory ceramic material, which is insoluble in water or hydrochloric acid and very stable in vacuum. LaB6 cathode Stoichiometric samples are colored intense purple-violet, while boron-rich ones (above LaB6.07) are blue. Ion bombardment changes its color from purple to emerald green. LaB6 cathode is a superconductor with a relatively low transition temperature of 0.45 K.

Borides are hard, high-melting materials with metal-like conductivity, and they are stable to nonoxidizing acids but break down in strong oxidizing agents and strong alkalis. Borides are used in semiconductors, superconductors, diamagnetic, paramagnetic, ferromagnetic, anti-ferromagnetic, turbine blades, and rocket nozzles. High Purity (99.999%) Lanthanum Boride Sputtering Target nanopowder forms may be considered.
