Abstract
1,243,906. Cadmium sulpho-selenide. HERCULES Inc. 25 Nov., 1969 [26 Nov., 1968], No. 57702/69. Heading C1A. A cadmium sulpho-selenide pigment is made by heating an aqueous slurry of crude cadmium sulpho-selenide at 90-160 C. in presence of 1000-2000% (by wt. of dry crude) of alkali metal hydroxide, and 50-150% (by wt. of dry crude) of an alkali or alkaline earth metal nitrate, carbonate, sulphate, halide or aluminate. The product is essentially transparent, and has an X-ray diffraction pattern characteristic of a cubic structure, and having d-spacings of relative intensity more than 25% at about 3À4, 2À1 and 1À8 Angstroms, any d-spacings at about 3À6, 3À2 and 1À9 Angstroms having a relative intensity less than 25%. Such dspacings may be entirely absent. In examples, aqueous slurries of crude cadmium sulphoselenide made by adding solution of sodium sulpho-selenide to aqueous slurries of cadmium nitrate and cadmium carbonate, are heated with sodium hydroxide and sodium nitrate.
