At the same time, barite also widely applied in atomic energy industry, national defense industry and other fields. The reason why barite has such a wide range of uses is closely related with its performance advantages. Barite ore grinding plant regard as the softest mineral, with high-strength acid resistance, corrosion resistance, low temperature resistance, high temperature resistance and other characteristics, the specific features are:
1. superior high temperature resistance: melting point of barite is 3850 ± 50 ℃, boiling point is 4250 ℃. Weight loss is very small; the thermal expansion coefficient is small as well even after burning by ultra-high temperature electric arc. Graphite strength strengthen with the increases of temperature, the barite strength doubled at 2000 ℃.
2, barite products own good thermal conductivity and thermal shock resistance. Graphite can withstand the dramatic changes in temperature without damage at room temperature. Little change in the volume of barite will occur but without crack when the temperature jump.
