LOW COST MELT AND CAST MATERIALS ON BASE OF ALUMINA-ZIRCONIUM-SILICA AND METHOD FOR USING THEM Russian patent published in 2006 - IPC C04B35/657 C04B35/106 

FIELD: designs of glass melting furnaces.

SUBSTANCE: melt and cast materials on base of alumina-zirconium - silica contain, mass %: Al₂ O₃, 45 - 65; Zr0₂, 10.0 - 29.0;_{SiO2, 20.0 - 24.0 at relation SiO2/(Na2O + K2O), 4.5 - 8.0, the balance matters, 0.5 - 4.0. Such materials may be made of rejected products or from recovered waste materials and they may be used for making construction of glass melting furnaces, namely cross like members of regenerators.}

EFFECT: lowered cost of raw materials, high operational properties of products.
