Hello, Welcome to Shanxi Xinyufeng Technology Co., Ltd.!
Product Name: Chromium nitrate
CAS No.: 7789-02-8?
Molecular formula: Cr(NO3)3.9H2O
Molecular weight: 400.148
Physical and chemical properties: Chromium nitrate has anhydrous and various hydrates. The anhydrous is a light green powder. The common nonahydrate is a purple monoclinic crystal. It dissolves in its own crystal water at 66.3°C and boils and decomposes at 125.5°C.?Hydrated chromium nitrate weathers in the air, loses part of the crystal water, and is easily deliquescent.?Chromium nitrate nonahydrate is easily soluble in water, acid, alkali, ethanol and acetone.
Uses: Used to prepare other inorganic and organic chromium compounds, prepare catalysts and carriers, used as corrosion inhibitors and mordants, and used in glass industry and ceramic glaze.
Packing: Chromium Nitrate Nonahydrate·Packing is 25kg plastic bag lined woven bag, or according to customer requirements.
Technical parameters: Q/YLB-2005-23
