Study of Sodium Silicate System Firing During Glass Ceramic Foam Preparation

Resumo

The effect of temperature on foaming a mixture of diatomite and sodium hydroxide solution during glass ceramic foam preparation is studied. Composite foaming temperature is established conforming to optimum structural porosity and average specimen density required for heat insulation materials. The effect of temperature on the content within specimens of free sodium hydroxide is analyzed, and its reduction with an increase in temperature is revealed. The practical significance of this research is demonstrated on the example of preparing granular glass ceramic foam.
