Cerium Hexaboride Powder Description

Cerium Boride, also called Cerium Hexaboride or CeB6, is a refractory ceramic material. The principal use of cerium hexaboride is a coating of hot cathodes or hot cathodes made of cerium hexaboride crystals. It usually operates at a temperature of 1450 °C.

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.
