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; Related Categories: Chemical Mineral Raw Materials; Inorganic Chemical Products; Plant Extracts; Pigments; Raw Materials. Dolomite powder is produced by processing dolomite ore through beneficiation, coarse crushing, medium crushing, powdering, grading, and packaging. 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 pharmaceutical products, and as an acid neutralizer in soil. It can also be used as a metallurgical flux, construction stone material, refractory material, and as an ingredient in ceramics and glass. It can also be used to refine magnesium metal. It is a widely used inorganic filler material and an excellent performance enhancer, widely used in: putty powder, white paint, paints, plastics, rubber, papermaking, coatings, feed, daily chemical products, glass, ceramics, wastewater treatment, and steel mill desulfurization fields. Our factory produces various specifications of ultra-fine heavy calcium carbonate powder (heavy calcium powder, calcite powder) with uniform particle size distribution, high whiteness, and stable chemical composition.
