Ultrafine dolomite powder
(1).jpg) | The main component of dolomite powder is magnesium calcium carbonate, and the crystal belongs to the carbonate mineral of the cubic system, which is white. The crystal structure of dolomite is similar to that of calcite. The crystal form is rhombohedron, the crystal face is often bent into saddle shape, and the polycrystalline is common, mostly in massive and granular aggregate. The cleavage of the three rhombohedrons is complete and brittle. Mohs hardness is 3.5-4, specific gravity is 2.8-2.9, and mineral powder reacts slowly in cold dilute hydrochloric acid. |
