A dense-sintered protoenstatite ceramics based on fluorinated talc was obtained. Influence of BaO and Al2O3 additives on the sinterability, structure and strength of ceramics was investigated. It makes possible to reduce the sintering temperature to 1225 – 1250 °C due to formation of glassy phase. Additive of ZnO intensifies solid phase sintering at 1320 °C.
It significantly improves compressive strength of ceramics up to 660 MPa that exceeds the strength of traditional steatite materials by 3 times.
