Manganese Carbonate

Feed grade cas 598-62-9 cas 598-62-9 manganese carbonate  manganous carbonate(industrial grade) is rosy triangle crystal or amorphous brown powder. Calcined in the pyrolusite powder direct acidification method, which can shorten process, lower cost and reduce pollution to environment; widely used in ferrite, desulfurizatio, porcelain glaze, varnish, manganese salt, fertilizers, pharmacy and machine parts and agriculture.
