Shanghai Yuejiang chemical products Co., Ltd.   

Yue Jiang card - manganese carbonate (industrial grade) is the use of soft manganese ore direct acidification (two ore method), soft manganese ore is calcined into manganese oxide and then acidified, reduces the calcining process, saves equipment investment, reduce environmental pollution, and reduce the cost. Products for the rosy trigonal rhombohedral or amorphous light brown powder. The specific gravity of 3.125, almost insoluble in water, but slightly soluble in CO2 containing water. Soluble in dilute inorganic acid, slightly soluble in common organic acid salt, insoluble in liquid ammonia. Stable in dry air, wet oxidation, the formation of three oxidation two manganese and gradually turned into a black, when heated exothermic decomposition of CO2, and when the water azeotrope
