METHOD OF FOAM-GLASS MANUFACTURING Russian patent published in 2013 - IPC C03B19/08 C03C11/00 

Abstract RU 2490219 C1

FIELD: chemistry.

SUBSTANCE: invention relates to heat-insulating materials, in particular to foam-glass. Crushed zeolite-containing ore with NaOH water solution with the following ratio, wt %: zeolite-containing ore - 75-80, NaOH - 15-20. Raw mixture is granulated, granules are dried, kept in the air for 1-4 days. Foaming is performed at temperature 680-800°C.

EFFECT: extension of range of foam-glass density from 150 to 600 kg/m3 and creation of method of manufacturing foam-glass, safe for furnace equipment and environment.
