introduce:
Dolomite is a carbonate mineral, namely iron dolomite and manganese dolomite. Its crystal structure is similar to calcite, usually rhombohedral. Dilute hydrochloric acid will slowly foam when exposed to cold. Some dolomite appears orange under cathode rays. Dolomite is the main mineral composition of dolomite and dolomitic limestone. It is mainly used as a flux for basic refractories and blast furnace ironmaking. calcium magnesium phosphate fertilizers and magnesium sulfate; and raw materials for glass and ceramics.
Dolomite can be used as refractory inner layer, slagging agent, cement raw material, glass flux, kiln industry, chemical fertilizer, architectural decorative stone, paint, pesticide, medicine for steelmaking and reforming furnace, etc. It can be used in building materials, ceramics, glass and refractory materials, chemical industry and agriculture, environmental protection, energy saving and other fields.
Various quality dolomite series products: dolomite raw ore, dolomite sand 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-80 mesh, 80-120 mesh, dolomite powder 10 mesh, dolomite super Fine powder 140 mesh, 325 mesh, 600 mesh, 1000 mesh, 1600 mesh.
Dolomite is decomposed into a mixture of carbon dioxide, calcium oxide and magnesium oxide when heated to 700-900 °C, which is called caustic magnesia marble, which is easy to react with water. When Biyun is calcined at 1500°C, magnesium oxide becomes periclase, and a-CaO calcium oxide becomes crystal, with compact structure, strong water resistance, and refractoriness up to 2300°C.
