METHOD OF PRODUCING GLASS-CERAMITE Russian patent published in 2011 - IPC C03C10/00 C04B35/16 

FIELD: chemistry.

SUBSTANCE: invention relates to production of glass-ceramite used for external and internal facing of walls of buildings and other structures. The method of producing glass-ceramite involves preparing and batching crude components, mixing said components, moulding a substrate from the obtained mixture, forming a decorative layer on the substrate and roasting. The substrate is moulded from a mixture which contains the following in wt %: crushed glass 45.0-50.0; clay 10.0-15.0; pearlite 35.0-45.0. Pearlite is first expanded and saturated with 3-5% solutions of cobalt, nickel, manganese or copper nitrate solutions and dried to moisture content of not more than 9%. The decorative layer is obtained by surface glasing the roasted substrate until formation of a glass film.

EFFECT: obtaining quality glass-ceramite with a decorative finishing coat which is strongly bound to the substrate.
