Use of Amorphous Siliceous Rocks — Opokas to Obtain Foam Glass with Low Foaming Temperature

Аннотация

Information data on the use of amorphous siliceous rocks to obtain foam glass are presented together with the results of laboratory studies of the dependence of the foaming temperature on the melting temperature of the initial glass. A composition for low-melting glass based on opoka, soda ash, and boron-containing raw material (borax) in the ratios 1 : 0.3 : 0.35, respectively, was developed together with a method for obtaining block foam glass, which was used as a basis to obtain foam-glass blocks under laboratory conditions.
