Crystallites developed in steatite ceramics during sintering are the protoenstatite. The size of crystallites depends on temperature. During cooling protoenstatite crystallites invert to clinoenstatite ones, what is the cause of steatite ceramics deterioration and the loss on steatite mechanical endurance. The loss of mechanical endurance is strictly correlated with the degree of proto to clinoenstatite inversion. It was find out that there is much greater tendency for large protoenstatite to invert to clinoenstatite than for small ones. The temperature 1350 °C was find optimal for formation small, well crystallized protoenstatite crystals. This is also the temperature for which the temperature of protoenstatite to clinoenstatite inversion is the lowest and it is 250 °C.
