METHOD OF PRODUCING GLASSCERAMIC MATERIAL Russian patent published in 2011 - IPC C03C10/06 

FIELD: chemistry.

SUBSTANCE: method relates to production of construction materials, particularly to use of ash from refuse incineration plants for processing solid domestic wastes, followed by recycling thereof in production of highly efficient and environmentally safe construction articles. The method is characterised by that glass mass is obtained from a mixture containing up to 70% ash, 20-40% silica-containing component and up to 20% alkali-containing component. The obtained articles undergo crystallisation in a single step at temperature 900-1100°C and holding for 60-120 minutes or in two steps at temperature 700-850°C and holding for 30-60 minutes and at temperature 900-1100°C for 60-120 minutes.

EFFECT: high chemical resistance, wear resistance, prevention of water absorption and environmental safety of the obtained glassceramic material.
