Product Description

471-34-1 Calcium carbonate Fine Powder

Product Overview

Calcium carbonate is an inorganic compound commonly known as: gray stone, limestone, stone powder, marble and so on. Ingredients: Calcite, chemical formula is CaCO3, neutral, insoluble in water, soluble in hydrochloric acid. It is a common material on the earth. It is found in rocks such as meteorites, calcites, chalk, limestone, marble, travertine, etc. It is also the main component of animal bones or shells. Calcium carbonate is an important building material that is widely used in industry. Calcium carbonate is produced by the combination of calcium ions and carbonate ions, so it is both a calcium salt and a carbonate salt. White solid, odorless, odorless. There are two forms of amorphous and crystalline. Crystalline type can be divided into orthorhombic and hexagonal crystals, columnar or diamond. The relative density is 2.71 to 825-896.6°C, and it decomposes into calcium oxide and carbon dioxide at about 825°C. Melting point 1339°C, melting point 1289°C at 10.7 MPa. Hard to dissolve in water and alcohol. Reacts with dilute acid and emits carbon dioxide at the same time, showing an exothermic reaction. Also soluble in ammonium chloride solution. Almost insoluble in water.
