The effect of diopside on the sintering temperature, structure and properties of low-temperature electrical porcelain has been investigated. In the porcelain mass, 12.5 & # 37; by weight of diopside concentrate, which is 10 & # 37; diopside CaMgSi 2 O 6 , excluding quartz (7.2 & # 37;) and reducing the
content of clay components by 5.3 & # 37 ;. Decrease in firing temperature
by 100 & # 176; С & ndash; up to 1220 & # 176; C and an increase in bending strength by 30 & # 37; up to 73 MPa due to reaction sintering during the interaction of diopside with decomposition products of clay components with the formation of anorthite and cordierite
