Chromium Boride Powder（CrB2） 

Product Name: chromium diboride

Chromium diboride: b2cr

Molecular weight: 73.62

English Name: chromium border (CrB2)

EINECS：234-499-3

Density: 5.6g/ml

Flash point: melting point: 1550 ℃

CAS:12006-80-3

Molecular weight: 112.9969

Properties: insoluble in water, soluble in molten sodium peroxide

Application: used as wear-resistant, high temperature oxidation resistant coating and neutron absorption coating in nuclear reactor. It is used for ceramics. It is melt sprayed on metal and ceramic surfaces to form wear-resistant and corrosion-resistant films. Used for spraying semiconductor film. Chrome borate and alumina sintered or hot pressed in micro oxidation atmosphere have practical value of high temperature wear resistance.

Synthesis method:

Pure metal process: chromium and an appropriate amount of boron powder are heated at 1600 ℃ in vacuum or inert atmosphere or sintered at 1150 ℃ for 48 ~ 72h. Chromium borate CRB, cr2b, cr3b2, cr3b4 and CrB2 are formed. After hot pressing at high temperature, CrB2, CRB or cr3b4 can be formed.
