The chemical composition is CaMg[CO3]2, the crystal belongs to three square system carbonate mineral. The crystal structure of dolomite is similar to that of calcite, the crystal shape is rhombohedral, and the crystal surface is often bent into saddle shape. White marble is white, because it contains other elements and impurities sometimes greyish green, gray yellow, pink color, luster glass. The three groups were full cleavage and brittle. Mohs hardness of 3.5-4, the proportion of 2.8-2.9. Mineral powders react slowly in cold, dilute hydrochloric acid.
Dolomite is widely used, it is a chemical, glass, enamel, welding materials, metallurgy, refractory, dolomite powder (calcium carbonate powder) architectural coatings, ultrafine Shuangfei powder as a filler of plastic
Identifying characteristics: with hardness larger in the cold, slow in dilute hydrochloric acid and other characteristics, can be distinguished from similar calcite.Dolomite is the main mineral component of dolomite and dolomitic limestone. Dolomite can be used as metallurgical flux, refractory material, building material and ingredient of glass and ceramics
