Beschreibung
Zusammenfassung:	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 SnxCa1-xLa2-2XS4-2x where 0.005 ëñ x ëñ 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. ^ 2 cl, 3 ex, 1 tbl Изобретение может быть использовано в лакокрасочной промышленности, производстве пластмасс, керамики, строительных материалов. Неорганический пигмент на основе сульфида металла, включающий редкоземельный металл, представляет собой сложный сульфид общего состава SnxCa1-xLa2-2xS4-2x, где 0,005≤х≤0,4. Изобретение позволяет получить пигменты широкой цветовой гаммы от лимонно-желтого до бордового, сохраняющие свой цвет в течение длительного времени, термически стабильные и экологически безопасные. 1 з.п. ф-лы, 1 табл.
