Use of Self-Propagating Crystallization Phenomenon in the Production of Glass Ceramic Materials

摘要

The possibility of using self-propagating crystallization accompanied by the propagation of the crystallization heat wave front in the transition of foam silica produced on the basis of compositions in the system CaO - MgO - A1_2O_3 - SiO_2 by the reducing melting method with melt separation and subsequent cooling of the silicate component under a thermal shock from the x-ray-amorphous state to the crystalline state is studied. The characteristics of the thermal wave are identified, the dependence of the velocity of propagation of the thermal wave on the dispersion of the foam silicate and molding pressure is established.
