Using of self-propagating crystallization upon glass-ceramics production

The possibility of using self-propagating crystallization, accompanied by the propagation of the front of a thermal crystallization wave, during the transition of foam silicate obtained on the basis of the compositions of the CaO - MgO - Al ₂ O ₃ - SiO _{2 system} by the method of reduction melting with the separation of the melt and subsequent cooling of the silicate part in the thermal shock mode, from the X-ray amorphous state to the crystalline state. The characteristics of the heat wave are given, the dependence of the speed of propagation of the heat wave on the dispersion of the foam silicate and the molding pressure of the products is established.
