Zinc cadmium sulfide

An instance of cadmium-zinc sulfide (Cd , Zni i S) cathodic electrodeposition can be found in the work of Morris and Vanderveen [130]. These researchers managed to obtain polycrystalline Cd , Zni i S films from stirred aqueous solutions (pH 2,... [Pg.107]

The reaction finished within 1 h at 26°C.. They used seed crystals of CdS to promote the uniformity of the final product, and analyzed the growth kinetics using Nielsen s chronomal. The isoelectric point in terms of pH was determined to be 3.7 by electrokinetic measurement. They also prepared zinc sulfide (ZnS polycrystalline spheres), whose isoelectric point in pH was 3.0 (2), lead sulfide (PbS monocrystalline cubic galena) (3), cadmium zinc sulfide (CdS/ZnS amorphous and crystalline spheres) (3), and cadmium lead sulfide (CdS/PbS crystalline polyhedra) (3), in a similar manner.

Production. The raw material for the production of cadmium yellow pigments is high-purity cadmium metal (99.99 %), cadmium oxide, or cadmium carbonate. If the metal is used it is first dissolved in mineral acid. A zinc salt is then added to the solution the amount added depends on the desired shade. The zinc salt is followed by addition of sodium sulfide solution. An extremely finely divided cadmium sulfide or cadmium zinc sulfide precipitate is formed, which does not possess any pigment properties. This intermediate product can also be obtained by mixing the cadmium or cadmium-zinc salt solution with sodium carbonate solution. An alkaline cadmium carbonate or cadmium zinc carbonate precipitate is formed which reacts in suspension with added sodium sulfide solution. [Pg.107]

The cadmium pigments (cadmium-/zinc sulfide and cadmium sulfide/-selenide) are exempted from labelling. The cadmium pigments are slightly soluble in diluted acids and the soluble cadmium is bioavailable. Therefore some cadmium pigment producers are labelling their cadmium-/zinc sulfide and cadmium sulfide/-selenide pigments like the cadmium compounds. [Pg.112]

Developed in response to the need for stable lighter shades of the cadmium pigments, methods involving calcining a mixture of cadmium and zinc sulfides with either zinc or magnesium oxide were used (Laurie, 1914 cf. Fiedler and Bayard, 1986). However, the principal modern approach is to form cadmium zinc sulfide, Cdi j Znj,S. Here, cadmium and zinc salts with the same anion... [Pg.73]
