CHROMIUM POTASSIUM SULFATE Chemical Properties,Usage,Production

Chemical Properties Also known as chrome alum and chrome potash alum, CrK(S04)2·12H20 is dark, violet-red crystals that are efflorescent and soluble in water. Derived by reducing potassium dichromate in dilute sulfuric acid with sulfurous acid. Used in tanning(chrome-tan liquors), textile dye(mordant), photography (fixing bath)and ceramics.
Description Chromium potassium sulfate is a crystallinecompound whose color may range from violet-red to black.Molecular weight =287.3; Freezing/Melting point =89℃;Soluble in water
Chemical Properties Chromium potassium sulfate is a crystalline compound whose color may range from violet-red to black
Uses Tanning (chrome-tan liquors), textile dye (mordant), photography (fixing bath), ceramics.
General Description The higher the pH more is the chromium (III) (crystal growth suppressor) adsorbed, on the surface of potassium sulfate crystal powder which is suspended in saturated solutions.
Hazard Toxic by ingestion.
Safety Profile Mutation data reported. Questionable carcinogen. When heated to decomposition it emits toxic fumes of K2O. See also CHROMIUM COMPOUNDS and SULFATES.
Potential Exposure This material is used in tanning of leather; dyeing of fabrics; manufacture of glues and gums, chromium salts; ink, photographic emulsions, and ceramics
