Dolomite - Nature
Open Data Verified Data
is a carbonate rock with Dolomite as the main mineral component. The composition formula is CaMg(C03)2. Theoretical Content: Mg0 content is about 22%, Ca0 content is about 30%, and the rest is 48%. The three-party crystal system. The crystal is rhombohedral. The aggregates are usually granular. Gray-white. Sometimes microstrip light yellow, light brown, light green. Glass gloss. Mohs hardness 3.5~4. The relative density ranged from 2. 85 to 3.2. Slow foaming when cold with dilute hydrochloric acid. Insoluble in water. When calcined to 700-900 °c, carbon dioxide is lost to form a mixture of calcium oxide and magnesium oxide, and when calcined to 1500 °c, magnesium oxide becomes periclase, and calcium oxide becomes crystalline calcium oxide.
