Specifications
Product description:
; Malachite;
; Copper carbonate.
Product specification: Industrial grade
Molecular formula:CuCO3.Cu(OH)2
Molecular weight: 221.12
Physic-chemical Properties:
Peacock green tiny amorphous powder. the density is 3.85, and melting point 200 degrees.Insoluble in unboiled water or alcohol, and dissolved in acid to form the corresponding copper salts, soluble in cyanide, sodium hydroxide, ammonium salt and alkali carbonate to form copper complex. Will produce brown copper oxide when boiled in alkali metal carbonate solution, and dissolved to black copper oxide at 2000.Unstable in the hydrogen sulfide.Become more than a dozen chemical compound when in different ratio according to CuO:CO2:H2.and the molecular formula is CuCO3.Cu(OH)2.XH2O in industry manufacturing.the solubility in water is at 0.0008%, and with low toxicity when under decomposition temperature of 200-2200.
Product use:
Used as analytical reagents,to produce varied copper compound in inorganic salt industry,as organic synthesis catalyst in organic industry;as copper additive in electroplated Cu-Sn alloy coating industry and desulfurizer in crude oil storage,also widely used in wood preservation.
Packing&storage:
