FIELD: chemistry.
SUBSTANCE: method includes mixed grinding of prepared glass material, clay and a carbon gas-forming agent. Water is added to the obtained mixture and granules are formed therefrom. The granules are mixed with finely ground filings, foamed in a gas medium containing 1-3% CO at 830-850°C in a revolving furnace with inclination angle of 18-20°. After the foaming process, the granules in a pyroplastic state are moulded into a strip of a given shape. The strip is then fired at an initial temperature of 300-400°C with reduction to a final temperature of 80-90°C, cut, packed and stored.
EFFECT: simple technique, wider raw material base when producing foam glass-ceramic with improved operational properties.
