METHOD OF MAKING HOLLOW GLASS SPHERES, CRUDE MIXTURE FOR MAKING HOLLOW GLASS SPHERES Russian patent published in 2012 - IPC C03B19/10 

Abstract RU 2465223 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the industry of construction materials, particularly to production heat-insulating filler and aggregates for concrete, warm plasters, ceramics etc. The method involves continuous feeding of granular crystalline glass powder, ground together with a carbonate gas-forming agent and iron oxide, into the jet of a gas burner of a mould, cooling the moulded particles in a gas-air stream, separating said particles from the gas-air stream in separators, dividing the moulded particles into fractions. The crystalline glass used is glass ceramic or foamed glass wastes. The binder of the granular crude material used is aqueous solution of liquid glass.

EFFECT: obtaining strong alkali-resistant and water-resistant hollow glass spheres with low packed density.
