Dolomite Powder Chinese Name: Dolomite Powder Synonyms: Dolomite C.I. CAS No.: 7000-29-5 Molecular Formula: C2CaMgO6 Molecular Weight: 184.4008 EINECS No.: 230-274-9 Categories: Chemical Mineral Raw Material; Inorganic Chemical Product; Plant Extract; Plant Extracts; Inorganic Pigment; Pigment; Raw Material. Dolomite ore is processed through beneficiation, coarse crushing, medium crushing, powdering, grading, and packaging to produce dolomite powder. Dolomite is used in the chemical industry for manufacturing magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizer, as a filler in rubber and pharmaceuticals, and as a soil acidity neutralizer. It is also used as a metallurgical flux, construction stone material, refractory material, and as an ingredient in ceramics and glass. It can also be refined to produce magnesium metal. It is a widely used inorganic filling material, serving as an excellent performance modifier, and is extensively used in: putty powder, white paint, paint, plastics, rubber, papermaking, coatings, feed, daily chemical products, glass, ceramics, wastewater treatment, and steel mill desulfurization fields.
