The tribochemical treatment of glass and grains surface area as a crystallization activating factor and its influence on the crystal phase formation is a subject of the study. Sheet glass SiO2-CaO-Na2O as a material of extremely small crystallization ability has been used in the investigations. Tribochemical activating glass powder, pressed and heated at 750°C makes it possible to obtain glass-ceramic material containing quartz, devitrite and wollastonite crystals. During a prolonged heating time, up to 500 hours, devitrite and wollastonite content is diminishing and quartz becomes a main component of the material. Structural mechanism of tribochemical activated glass crystallization in its viscoelastic state as compared with liquid glass crystallization is considered.
