The results of a study of purified basalt from slime, impurities and hydroxides, changes in the chemical composition of basalt rock are presented.</p> <p>The prospects of heat treatment of a semi-finished product and obtaining multi-colored products from mineral raw materials is shown. It was found that the optimal firing temperature of the semi-finished product, the possible options for changing the external color and the criterion points of the thermal effect at which the basalt semi-finished product changes the external shade.</p> <p>These statements are of great scientific and practical interest in the fact that during the heat treatment of a semifinished product, basalt easily overheats and gradually acquires a different color, which occurs to a liquids temperature and allows the future to plan to obtain high-quality multi-colored products from basalts, for example, products for design.</p> Rashidova R K, Kurbanov Abdirakhim Ahmedovich, Aliyev T, Jiyanov A B, Turdieva O J, Nurmatov J T ##submission.copyrightStatement## Wed, 02 Sep 2020 00:00:00 +0800
