INORGANIC PIGMENT BASED ON METAL SULPHIDE Russian patent published in 2010 - IPC C09C1/00 C09C1/02 C01G1/12 C01B17/42 C01F17/00 C01G19/00

Abstract RU 2388773 C2

FIELD: chemistry.

SUBSTANCE: invention can be used in paint-and-varnish industry, in making plastic, ceramics and construction materials. The inorganic pigment based on metal sulphide which contains a rare-earth metal is a complex sulphide with general formula Sn_xCa_1-xLa_2-2XS_4-2x where 0.005 ≤ x ≤ 0.4.

EFFECT: invention enables to obtain pigments with wide range of colours from lemon-yellow to claret coloured, which retain their colour for a long period of time, are thermally stable and environmentally safe.
