COMPOSITION FOR PRODUCTION OF PYROCERAMIC COMPOSITE TILING MATERIAL AND METHOD FOR ITS PRODUCTION Russian patent published in 2009 - IPC C03C10/02 

FIELD: construction.

SUBSTANCE: as initial glass that is transformed into pyroceram in process of composition sintering, crushed glass is used of window or container glass. In order to transform glass into pyroceram, microsilica is used - waste of ferroalloy or other production. In order to give desired structure and texture to finished composition, it is reasonable to introduce natural or artificial sand in mixture with fraction of 0.315-1.25 mm. To colour the composition, it is reasonable to use compounds of transition metals or waste of production that contains such compounds. In order to produce crushed glass of window or container glass, their mixes are crushed until they may completely pass through sift of 0.315 mm, mixed with sand, microsilica and pigmenting substance, afterwards it is heated up to temperature of 820-890°C until complete transition of glass into melt condition, and then exposed to rolling or hot moulding (pressing). After moulding product is exposed to crystallisation, cooling and mechanical treatment, which consists in cutting of product edges and its grinding (polishing).

EFFECT: creation of environmentally safe composition and method for its production.
