Liaoning Heavy Calcium Powder, Haicheng Heavy Calcium Powder, Heavy Calcium Carbonate Powder, Liaoning Calcium Carbonate Powder, Haicheng Calcium Carbonate Powder, Ultra-fine Calcium Carbonate Powder

Calcium carbonate is produced through ore selection, coarse crushing, medium crushing, powdering, grading, and packaging. It is used in the chemical industry to manufacture magnesium, calcium magnesium phosphate fertilizers, light magnesium carbonate, granular fertilizers, as a filler in rubber and pharmaceuticals, and as an acid neutralizer for soil. It can also serve as a metallurgical flux, building stone, refractory material, and as an ingredient in ceramics and glass. It is also used to refine magnesium metal. It is a widely applicable inorganic filler material, excellent as a performance enhancer and widely used in: joint compound, white paint, paint, plastics, rubber, papermaking, coatings, feed, daily chemical products, glass, ceramics, wastewater treatment, and steel mill desulfurization fields.
