Developing physical and chemical foundations to manufacture mica phosphate materials for various science-based areas of engineering and construction industry

Abstract

Intensification of the existing technological processes as well as introduction of innovative technology are not conceivable without applying high-temperature electric heating. There is much concern about new generation materials with increased heat resistance, which can withstand the service temperature of 12000C for a long period of operation. The research aim: to develop the physical and chemical principles for manufacturing heat-resistant mica-phosphate materials with high performance characteristics. The objects of the research are compositions of powdered mica from various deposits with the aluminum-chromium-phosphate bounding component at the component ratio 1: 1. Research methods: a number of modern physical and chemical methods were used: x-ray phase and thermal analyses, as well as IR spectroscopy method. Research results: as a matter of the experimental studies and scientific generalization, the regularities in the “mica - phosphate bounding component” system are revealed. The parameters that allow obtaining heat-resistant mica-containing materials with high performance characteristics for a wide range of applications in various scientific based areas of engineering and construction industry are determined and improved.
