Because barite can be decomposed in molten steel and reacted with oxygen and metal oxides in molten steel to form carbon monoxide and silicon-containing slag. Therefore, it can be used as a purifying agent for smelting steel, that is, as a deoxidizer for steel making and a modifier for cast iron. This generally uses low purity barite mill to reduce costs. At the same time, it can also be used as a raw material for manufacturing silicon tetrachloride.
It is used as a heating element, a non-linear resistance element and a high semiconductor material. The heating element refers to a silicon carbon rod (suitable for various electric furnaces operating at 1100 to 1500 째 C), a non-linear resistance element, and various types of lightning protection valve sheets.
It is formulated into a far-infrared radiation coating or a far-infrared radiation dryer made of barite silicon plate.
