- Abstract
The article considers the possibility of replacing traditional mineral raw materials (dolomite and asbestos) to obtain thermal insulating material - sovelite - with technogenic raw materials, i.e. tails of polymetallic ores (dolomitebarium tails) and synthetic wollastonite, obtained on the basis of phosphoric slag. The research results allowed us to establish that the dolomite-barium "tails" can serve as a technogenic raw material base to obtain thermal insulating material - sovelite. The advantages of the proposed technology to obtain thermal insulating material -sovelite- in comparison with the traditional one allow for reducing energy costs for production due to the absence of stages of raw material extraction, crushing, and grinding, a reduced firing temperature, the absence of the stage of grinding the fired product since during firing there is waste dispersion, natural dolomite saving, replacement of expensive natural reinforcing material - chrysotile asbestos-with synthetic wollastonite, obtained on the basis of phosphoric slag. The use of synthetic wollastonite significantly improves the quality characteristics and increases the service life of the products.
