Dolomite Used for Ceramic Industry

The chemical composition of dolomite is CaMg(CO3)2, and the crystal is a carbonate mineral of the trigonal system. The crystal structure of dolomite is similar to that of calcite, the crystal form is rhombohedral, and the crystal plane is often curved into a saddle shape. Pure dolomite is white, sometimes gray-green, gray-yellow, pink and other colors due to other elements and impurities, and has a vitreous luster. The three groups of rhombohedrons are completely cleaved and brittle. Mohs hardness 3.5-4, specific gravity 2.8-2.9. Mineral powder reacts slowly in cold dilute hydrochloric acid.

Product Description

Introduction:

Dolomite is a carbonate mineral, there are iron dolomite and manganese dolomite respectively. Its crystal structure resembles calcite, and it is often rhombohedral. It will slowly bubble when exposed to cold dilute hydrochloric acid. Some dolomite emits orange-red light under cathode ray irradiation. Dolomite is the main mineral component of dolomite and dolomitic limestone. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical and agricultural, environmental protection, energy saving and other fields. It is mainly used as a flux for basic refractories and blast furnace ironmaking; for the production of calcium magnesium phosphate fertilizers and for the production of magnesium sulfate; and as ingredients for the production of glass and ceramics.

Economical use:

Dolomite can be used as refractory inner layer of reformer used in steelmaking, slagging agent, cement raw material, glass flux, kiln, fertilizer, stone for construction and decoration, paint, pesticide and medicine. It can be used in building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy saving and other fields.
