PROPERTIES:
Chromium is silvery white brittle metal with slight sky-blueness.Below 300°C,it keeps stable in oxygen,nitrogen and wet air.As temperature increasing,its oxidation reaction speeds up,but the reaction slows down after an oxidation film forms on its surface.When the oxidation film is damaged in 1200°C,its oxidation reaction speeds up again.Therefore,chromium is antioxidant below 1000°C.The roles of cold hydrochloric acid,cold nitric acid and sulphuric acid on chromium are faint,and so chromium prevents acidic corrosion.
APPLICATION:
It is widely used in powder metallurgy,welding materials,special alloy and other nonferrous alloy industries and fields.Its oxygen content is controllled below 0.05,applicable to military high-tech products.
