FIELD: chemistry.
SUBSTANCE: invention relates to production of ceramics, specifically to making ceramic pigments underglase and overglase ceramic paints for painting ceramic bodies and glase. The technical result is achieved due to that, in order to obtain a stoichiometric composition of helenite, aluminium oxide Al2O3 is added to the mixture which contains iron oxide Fe2O3 and silicate raw material - nepheline sludge. The said components are taken in the following ratio, wt %: niepheline sludge 59.0-61.5, Al2O3 25.0-33.5, Fe2O3 5.0-16.0. The temperature of pigment synthesis 1150-1250°C.
EFFECT: increased heat resistance of ceramic pigments and recycling alumina production wastes.
