Abstract

It is established that in principle opoka from the Kyngrakskoe deposit can be used as raw material for obtaining heat-insulating foam glass by a technology that eliminates the melting process. The optimal sintering temperature, powder dispersity and mass content of sodium hydroxide additive, which make it possible for amorphous foamed material to form from opoka during the heat-treatment process, are determined.

Article
It is shown that aluminosilicate rocks and materials can be used to make glass suitable for making foam glass. Characteristic moduli are proposed for evaluating the suitability of aluminosilicate materials for glassmaking and for the glass obtained. The batch compositions for making glass and foam glass are presented.
Article
Principles of producing foam glass rate considered. A correlation between structure and such properties as density, water absorption, strength, and thermal conductivity of materials obtained is demonstrated. The advantages, disadvantages, and prospects of a “cold” method for foam glass production are discussed.
