Properties of high-voltage porcelain with silica-containing raw material from Uzbekistan

The results of studies to determine the possibility of using local raw materials of Uzbekistan for the production of electrical ceramics are presented. The properties of ceramics are studied depending on the chemical composition of pegmatites of various deposits. It was determined that the electrical characteristics primarily depend on the content of oxides of alkaline elements in porcelain and, to a lesser extent, on the K ₂ O: Na ₂ O ratio in silica-containing raw materials.
