Abstract
Based on this article, high-voltage porcelain ceramics was prepared as local raw materials. According to state standard (GOST 7025-91), density, water absorption, and volume shrinkage were determined. A structural analysis was carried out using a scanning electron microscope, and an X-ray phase analysis was carried out on an Xpert PRO diffractometer. It was found, that in the initial state, ceramics consist of hexagonal (SiO2) and in a small amount of monoclinic phase, above a temperature of 1150 °С it consists of hexagonal (SiO2), an orthorhombic lattice, and also contains mullite (Al2Si2O13).
