CaCo3 calcium carbonate powder
Product Description
Precipitate calcium carbonate. It is made of high quality calcium carbonate(limestone) as raw material.It through calcine,digestion, carbonation, sedimentation,filtration, drying and crushing process and become.The products characteristic is high whiteness, high brightness, uniform distribution of particles,narrow diameter distribution etc.
Calcium carbonate occurs in nature as limestone in various forms, such as marble, chalk, and coral. It is probably the most widely-used raw material in the chemical industry. It has numerous applications, primarily to produce cement, mortars, plasters, refractories, and glass as building materials. It also is used to produce quicklime, hydrated lime and a number of calcium compounds. It is produced either as powdered or precipitated calcium carbonate. The latter consists of finer particles of greater purity and more uniform size. They also have many important commercial applications. Various grades of precipitated calcium carbonate are used in several products, such as textiles, papers, paints, plastics, adhesives, sealants, and cosmetics.
