Abstract

Clay and nonplastic types of raw materials necessary for electrotechnical porcelain synthesis, as well as wollastonite raw materials for additives were considered from among the minerals of the Republic of Kazakhstan; the compositions, properties, phase transformations during heat treatment of kaolins, white-burning refractory clays, quartz sands, feldspars and wollastonites were studied; a technology was developed for obtaining porcelain for electrical insulation with the use of mineralizing additives - wollastonites; porcelain’s structure and phase composition formation processes and its mechanical and dielectric properties were studied; optimal ratios of porcelain mixture components and amount of additives needed to improve the porcelain phase formation process by increasing the mullite crystals formation at lower temperatures compared with traditional porcelain were determined; first proved the possibility of obtaining electrotechnical porcelain with high properties from local natural types of mineral raw materials; the developed electrotechnical porcelain technology introduction will allow to solve the import substitution problem.
