The article deals with the perspectives of producing heat-resisting materials on the base of serpentine rocks (a by-product of asbestos production) and the factors preventing it. The section “Materials and methods” describes the methods used in the work and the characteristics of materials. The influence of orthophosphate acid concentration on strength, water resistance and heat resistance of magnesium phosphate cements are estimated. The concentrations of the acid providing the maximum limits of bending and compression strength are identified herein. The resistance of elaborated material to the influence of high temperatures and its water resistance are estimated herein. The phase composition of the developed material is defined and the article proves that there is no harmful gas emission at heating in the studied compositions. We showed the benefits of the scientific direction and research in this area.
