“…For enhancing the heat resistance of a composite it advisable to introduce modifying agents into micalex stock (up to 5-10%) that would reinforce composites obtained owing to creating additional centers of glass crystallization, enriching its binding substance with aluminium and silicon, which contributes to crystallization of sanidine, sillimanite, leucite and other minerals raising heat resistance of the composite. Magnesium oxide, wollastonite, furnace clinker, and corundum were used as modifying agents [21]. Heat resistance of heat-resistant micalex grows considerably if corundum is added Table 1 presents properties of heat-resistant micalex with different ratio of mass fractions of the main components.…”

Present-day materials science requires development of compositions and technologies for production of composites with enhanced physical and technical properties. One of requirements towards such materials is an elevated heat strength. Materials, earlier used in electrothermy (ceramics, porcelain, asbestos and items made of them), have operating temperature of 400-500°С, high cost, low mechanical strength and a number of other drawbacks. Therefore, development of heat-resistant, mechanically strong and inexpensive insulation materials is an immediate problem. Mica’s characteristics to the maximum extent meet the requirements to a filler for the composite materials. Its use would enhance electric and physical properties of composites, contribute to development of waste-free technology, thus favoring the environment. Objectives of the paper: development of technology for production of heat-resistant materials on the base of heat-proof mica and special glass with elevated softening point; study of the interaction between composite components and high-temperature medium; giving recommendations on technology for fabricating heat-resistant composites with enhanced physical and technical properties. Objects of study: specimens of heat-proof mica (phlogopite), wastes of abrasive production, modifiers, glasses with high softening point. Methods of investigation: methods of thermodynamic and quantum-chemical studies were used with involvement of a complex of state-of-art physical and chemical methods. Results of study: development of theoretical grounds for forming the heat-resistant composite materials on the base of experimental studies and scientific generalizations. The technology for production of new heat-resistant materials on the base of rational use of mineral raw material and production wastes is proposed.
