FLUX FOR CERAMIC PAINTS Russian patent published in 2008 - IPC C03C8/04 C03C1/04 

FIELD: chemistry.

SUBSTANCE: invention can be used in decorating the porcelain, faience and glass. The flux contains in mass percent: 2.0-5.0 of SiO₂; 9.0-13.0 of B₂O₃; 38.0-43.0 of ZnO; 6.0-8.0 of Na₂O; 8.0-12.0 of Al₂O₃; 1.0-2.0 of ZrO₂; 22.0-28.0 of CaO; 1.0-2.0 of F'. Coefficient of thermal expansion of flux is 87-98×10^-7°C^-1. The flux is reasonable to use with the coloring supplements at amount of 0.5-15.0 mass percent above the flux mass.

EFFECT: coefficient of thermal expansion of flux is increased.
