Ceramics for grinding bodies

Ceramic materials have been developed with a sintering temperature of 1475 - 1520 ° C, an average density of 3.55 - 3.75 g / cm ³ , a closed porosity of about 3% and an average tensile strength in three-point bending of 250 - 350 MPa, promising for use as grinding bodies. Pilot tests have shown that the developed ceramics are 10 to 15 times more durable when grinding ceramic paint than uralite grinding media. Tab. 1, bibliography: 2 titles.
