Mechanisms Of The Formation Of Gas Bubbles In Heat Treatment Of Glass-Silicate Tiles

Theoretical research has been done into the mechanisms of the formation of gas bubbles which takes place during the sintering of the glass granulation product under the conditions of heating its upper layer. It is shown that in the bubble, there is a possibility of an inverse thermal distribution which will lead to a thermal jump on its boundary. At the thermal processing temperatures, the presence of CO2 increases the effect of absorption of the radiation conditioned by the spectral zones. Experimentally, it has been proved that a thermal field inversion takes place in the presence of an inner diffusing layer joined to a clearly transparent one for the thermal radiation of the material.
