Manganese carbonate (feed grade) CAS NO.598-62-9

It is the use of pyrolusite powder direct acidification method (that is, two ore method), pyrolusite calcined into manganese oxide and then acidified, reducing the calcination process, greatly saving equipment investment, reducing environmental pollution, and reducing costs. Products are rose-colored triangular crystal rhombohedral or amorphous bright white brown powder. Specific gravity 3.125, almost insoluble in water, but slightly soluble in water containing CO2. Soluble in dilute inorganic acid, slightly soluble in common organic acid salts, insoluble in liquid ammonia. Stable in dry air, easily oxidized when wet, forming manganese trioxide and gradually turning black, CO2 is liberated when heated, and hydrolyzed when azeotrope with water. In boiling potassium hydroxide, manganese hydroxide is formed. Widely used in telecommunications equipment as ferrite raw materials, desulfurization catalyst, enamel pigment, varnish drying agent, manganese salt and catalyst manufacturing raw materials. Manganese carbonate is also used in fertilizers, medicine, mechanical parts and phosphating. Agricultural manganese carbonate as trace element fertilizer content can be slightly lower.
