摘要：

The effect of diopside on the sintering temperature, structure, and properties of low-temperature electrotechnical porcelain was investigated. Diopside concentrate in the amount 12.5 wt.%, which is 10% diopside CaMgSi2O6, was introduced into a porcelain body, excluding quartz (7.2%) and decreasing the content of clay components by 5.3%. It was determined that the firing temperature was lowered by 100 degrees C to 1220 degrees C and the bending strength increased by 30% to 73 MPa due to reactive sintering on the interaction of diopside with the decomposition products of the clay components and anorthite and cordierite were formed.
