|Title:||Hydronium ion formation during the hydrometallurgical formation of valentinite (Sb₂O₃)||Contributor(s):||Bernett, RD (author); Mitchell, A (author); Brown, TC (author)||Publication Date:||2004||DOI:||10.1023/B:JMSC.0000012947.67817.17||Handle Link:||https://hdl.handle.net/1959.11/168||Abstract:||Cubic antimony trioxide or senarmontite (Sb₄O₆) is used as an additive to facilitate the flame retardancy of plastics and other commercial materials. This retardancy is due to the propensity of antimony trioxide to form gas-phase antimony trihalide under flame conditions, which is in turn able to stabilize the free radicals in the flame. Orthorhombic Sb₂O₃ or valentinite shows similar properties as senarmontite, but is not normally used because it oxidizes from a white to gray color when exposed to air and sunlight . Such graying can impact on the coloring of plastics, paints and textiles, and so photo stable white senarmontite is the preferred choice.||Publication Type:||Journal Article||Source of Publication:||Journal of Materials Science, 39(3), p. 1075-1076||Publisher:||Kluwer Academic Publishers||Place of Publication:||Dordrecht, Netherlands||ISSN:||0022-2461||Field of Research (FOR):||030206 Solid State Chemistry||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 177
