Calcium carbonate is a versatile inorganic compound widely used in industries such as manufacturing, pharmaceuticals, agriculture, food processing, and environmental protection. In industry, it serves as a construction material and a filler for plastics; in medicine, as a calcium supplement; in agriculture, to neutralize acidic soil; in food, as an additive; and in environmental protection, for treating wastewater and waste gases. With its stable chemical properties, it serves as a fundamental raw material across numerous sectors.
Industrial Applications
Construction Materials: Calcium carbonate is a primary raw material for producing cement, lime, and gypsum, and is also used to manufacture artificial stone and floor tiles. Its high whiteness and fine particle characteristics enhance the strength and durability of construction materials.
Plastics and Rubber: As a filler, calcium carbonate reduces production costs while improving the hardness, impact resistance, and surface gloss of plastic products. In rubber, it enhances tensile strength and wear resistance.
Coatings and Papermaking: It serves as a white pigment and thickening agent in coatings, improving opacity and stability; in the papermaking industry, it is used to whiten paper and improve printability.
Medical
