产品代码 : ME-Cr-5N-PO
Chromium is a kind of lightweight metal with blue-silvery white color. It is lustrous, hard, and brittle with high corrosion resistance and a high melting point. Chromium metal is silvergray, lustrous, very dense, hard metal. It takes a high polish and has a high melting point. It is also odorless, tasteless and malleable and does not suffer from hydrogen embrittlement. Chromium metal is remarkable for its magnetic properties. it is the only elemental solid which shows antiferromagnetic ordering at room temperature (and below).
ATT specializes in producing high purity Chromium Powder with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard Powder particle sizes average in the range of- 325 mesh,- 100 mesh, 10-50 microns and submicron (< 1 micron). We can also provide many materials in the nanoscale range.

Applications of Chromium Powder
Chromium powder is available in powder form in 5 different sizes from stock. The main uses for chromium powder are electroplating, fuel, catalysts, alloys, and metal corrosion inhibitors.Packing of Chromium Powder
Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
ATTs’ Chromium Powder is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
