Introduction
Chromium is a metal with silvery white luster. It is odorless, non-toxic, chemically stable, ductile, and brittle with impurities. Metal chromium is generally characterized by surface passivation in acids. Once depassivated, it is easily soluble in almost all inorganic acids, but insoluble in nitric acid. The Metal Chrome Powder is produced by a variable current laser ion beam gas phase process, with the advantages of high purity, uniform particle size, complete surface structure, easy dispersion, large specific surface area, and high surface activity. Because of its high surface activity and excellent electrical conductivity, it is widely used in semiconductors, conductive coatings, chemical catalysts and solar energy absorbers. What’s more, it can also be used for powder metallurgy of chromium related targets, diamond tools, electrical alloys, welding materials, aluminum alloy additives, etc. It receives a good reputation among customers all over the world because of high cost effective.
