FIELD: chemistry.
SUBSTANCE: invention relates to production of foamed glass. Method of foamed glass production includes mixing of cullet, zinc oxide and carbonate gas-forming agent at following ratio of components, wt. %: carbonate gas-forming agent 0.5–5.0, zinc oxide 0.5–1.5, scrap glass is the rest. Obtained mixture is heated in furnace to temperature of 600–620 °C to glass particles softening is sintered in the temperature range from 620 °C to 720 °C, foamed for 25–40 minutes in range of temperatures from 720 °C to 871 °C with subsequent cooling in temperature range from 880 °C to 30 °C.
EFFECT: technical result is higher open porosity properties and, consequently, high water saturation.
