SMC is a global supplier of Cerium Hexaboride Disc (CeB6 Disc) with competitive prices and excellent service. All sizes of CeB6 ceramic parts are finished with fine grinding, regular appearance, and high dimensional accuracy. Other customized shapes of CeB6 ceramic are available upon request.
Cerium Hexaboride (CeB6, also known as Cerium boride) is an inorganic chemical. It is a refractory ceramic material, which is insoluble in water or hydrochloric acid and very stable in a vacuum. Stoichiometric samples of CeB6 have a blue metallic luster. CeB6 is also a superconductor and semiconductor with a relatively high melting point of 2552 ℃.
Cerium Boride or (Cerium Hexaboride) is generally immediately available in most volumes. Borides are all hard, high-melting materials with metal-like conductivity. They are stable to nonoxidizing acids but break down in strong oxidizing agents and strong alkalis.
