Liaoning Heavy Calcium Carbonate Powder is produced by grinding marble and calcite through a Raymond mill, boasting a whiteness of 93-96% and a calcium carbonate content of 97.3-98%. Mesh: Marble powder. Chinese name: Marble powder; Synonyms: Marble rock; 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 products; Plant extracts; Inorganic pigments; Pigments; Raw materials. The marble ore is processed through beneficiation, coarse crushing, medium crushing, powdering, grading, and packaging to produce marble powder. Marble is used in the chemical industry to manufacture magnesium, calcium magnesium phosphate fertilizers, light magnesium carbonate, as a filler for rubber, and as an acid neutralizer for soil. It is also used as a metallurgical flux, construction stone, refractory material, and as an ingredient in ceramics and glass production. Metal magnesium can also be refined from it. It is a widely used inorganic filling material, serving as an excellent filler and performance enhancer, widely utilized in: spackling powder, lime whiting, paints, plastics, rubber, papermaking, coatings, feed, daily use items, 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), which features uniform particle size distribution, high whiteness, and stable chemical composition.
