About Chromium Diboride CrB2 Powder:
Chromium diboride chemical formula is CrB2, which is one of six stable chromium di-boron, melting point 1760 ° C, good antioxidant properties, high-temperature strength. Boron with metals, certain non-metallic (such as carbon) formation of dual compounds. The usual formula MMBN is usually used, generally a complex compound, and does not follow the pricing rules. In addition to zinc (Zn), cadmium (Cd), mercury (Hg), gallium (Ga), indium (In), β（T1）, germanium (Ge), tin (Sn), lead (Pb), bismuth (Bi) Other metals can form boron. They are all crystals with high hardness and melting point, and the chemical properties are stable. The heat concentrated nitric acid cannot dissolve it, which can be directly compounded by the elements, or prepared with an active metal reduction oxide, used as fire, grinding and superconducting material.

How is Chromium Diboride CrB2 Powder produced?
Chromium is heated at a vacuum or an inert atmosphere at 1600 ° C or sintered at 1150 ° C for 48 to 72 h, and boride chromium CrB, Cr2b, Cr3b2, Cr3B4, CrB2, and after hot press at high temperatures, CrB2 can be formed. , CrB or Cr3B4.
Application of Chromium Diboride CrB2 Powder:
Chromium Diboride can be used as a refractory material;
Due to the high melting point of Chromium Diboride, very hard, corrosion resistance is very high;
Chromium Diboride is used as a metallurgical additive;
Chromium diboride as a sputtering target for the production of a film;
Chromium diboride can be a wear-resistant and semiconductor film.
Storage Condition of Chromium Diboride CrB2 powder:
The damp reunion will affect CrB2 powder dispersion performance and using effects, therefore, chromium diboride CrB2 powder should be sealed in vacuum packing and stored in cool and dry room, the chromium diboride CrB2 powder can not be exposure to air. In addition, the CrB2 powder should be avoided under stress.
Packing & Shipping of Chromium Diboride CrB2 powder:
We have many different kinds of packing which depend on the chromium diboride CrB2 powder quantity.
Chromium diboride CrB2 powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Chromium diboride CrB2 powder shipping: could be shipped out by sea, by air, by express, as soon as possible once payment receipt.
