Title (EN) CORUNDUM CRYSTAL STRUCTURE PIGMENTS WITH REDUCED SOLUBLE CHROMIUM CONTENT
(FR) PIGMENTS À STRUCTURE CRISTALLINE DU CORINDON À TENEUR RÉDUITE EN CHROME SOLUBLE
Abstract: front page image
(EN)The potential for release of soluble chromium (Vl) ions in the production or processing of certain pigments is reduced by use of certain additives. The additives include aluminum metaphosphate, aluminum fluoride, tungsten oxide, tungstic acid, and mono-ammonium phosphate. The pigments are those which contain chromium and have a corundum crystal structure.
(FR)Le potentiel de libération d'ions chrome (VI) solubles lors de la production ou du traitement de certains pigments est réduit grâce à l'utilisation de certains additifs. Les additifs comprennent le métaphosphate d'aluminium, le fluorure d'aluminium, l'oxyde de tungstène, l'acide tungstique et le phosphate de mono-ammonium. Les pigments sont des pigments qui contiennent du chrome et qui ont une structure cristalline du corindon.
