FIELD: electric engineering. SUBSTANCE: porcelain mass comprises, mas. %: wollastonite, 4-10; quartz-sericite stone, 50-66; high-melting clay, 5-12, kaolin, the balance. Porcelain articles being manufactured of proposed mass and roasted at 1280-1320 C have increased mechanical strength (their bending strength being more 1300 kg/cm2), their heat resistance is more 180 C, electric strength is up to 30 kV/mm. EFFECT: decreased roasting temperature by about 50 C. 2 tbl
