Detailed
About Chromium Cr powder:

Chromium Cr powder with is a kind of Elementary powderwithNano-chromium powder laser beam through a variable current gas-phase process to produce high purity,  uniform particle size, surface structure intact, easily dispersed, large surface area, high surface activity. The chemical formula of Chromium Cr powder is Cr . They are mainly used in the semiconductor, conductive coatings, chemical catalysts and solar absorber.

 


Advantages of Chromium Cr powder:
Chromium Cr powder has the soluble in hot concentrated sulfuric acid and aqua regia, but insoluble in water. It is combustible in case of open flame and high heat.
