Composition of technical ceramics of low-temperature sintering for grinding bodies

Optimal material and charge compositions of technical ceramics for grinding media have been developed. It has been established that the best indicators of the material composition and technological properties have prototypes of ceramic masses with alumina content from 55,25 to 64,93 wt. % for obtaining mullite ceramics, as well as 65,79 to 74,21 wt. % for obtaining mullite-corundum ceramics. The possibilities of using kaolins of various grades for the development of new compositions of grinding media for low-temperature sintering are shown.
