Lanthanum Hexaboride Disc Description

Lanthanum Boride, also called Lanthanum Hexaboride or LaB6, is a refractory ceramic material. It has a high melting point of 2210 °C, and is insoluble in water and hydrochloric acid. And it is stable in vacuum.

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.
