Product Code :
Cerium Hexaboride rod, CeB6 Discs 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. Cerium boride rod, also known as cerium hexaboride disc or CeB6, is a refractory ceramic material. The main use of cerium hexaboride is a hot cathode coating or a hot cathode made of cerium hexaboride crystals. It usually operates at a temperature of 1450 ° C.

Packing of Cerium Hexaboride Rod （ CeB6 Rod）
Standard Packing:
Sealed bags in carton boxes. Special package is available on request.
As a ceramic material, CeB6 is quite fragile in a lot of cases. The CeB6 rod are usually held in plastic bags by vacuum, and protected with heavy foam.
ATTs’ CeB6 rod is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
