Yuanjiang Brand - manganese carbonate (industrial) is to use soft manganese ore powder direct acidification method (that is, the two mining method), calcined into soft manganese ore manganese oxide to acidification, reduced the calcination process, greatly saves equipment investment, reduce the pollution of the environment, and reduce the cost.Product is the rose Triangular crystal system rhombohedron or amorphous bright white brown powder.Specific gravity 3.125, almost insoluble in water, but soluble in water containing CO2.Soluble in dilute mineral acid, slightly soluble in ordinary organic acid salt, insoluble in liquid ammonia.Stable in dry air, wet easy oxidation, the formation of manganese oxide and gradually become black, heat liberation in the CO2, and water azeotropic hydrolysis.In the boiling of potassium hydroxide, manganese oxide generated hydrogen.Widely used in telecommunications equipment Used as the material of ferrite, desulfurization catalyst, enamel paint, varnish drier, manganese salt catalyst manufacture and raw materials.In fertilizer, medicine, machinery parts, and also need to use the manganese carbonate in phosphating treatment.Agricultural use manganese carbonate as trace element fertilizer its content can be slightly lower.
