Código de producto :
Cerium Hexaboride part, CeB6 part 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 part, also known as cerium hexaboride part 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 Part
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 part are usually held in plastic bags by vacuum, and protected with heavy foam.
E FORUs’ CeB6 part is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
