Cerium Boride, also called Cerium Hexaboride or CeB6, is a refractory ceramic material. Nextgen Advanced Materials supplies Cerium Hexaboride Powder with high quality and fast delivery, and customized products are also available.
As the professional manufacture, we would like to provide you high quality Nextgen Cerium Hexaboride Powder. And we will offer you the best after-sale service and timely delivery. 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 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.
