Antimony tetroxide is an inorganic compound with the formula Sb 2 O 4.This material, which exists as the mineral cervantite, is white but reversibly yellows upon heating. The material, with empirical formula SbO 2, is called antimony tetroxide to signify the presence of two kinds of Sb centers.
Recovery of tungsten from waste material by ammonium For recycling of tungsten from waste material or residual material comprising impurified tungsten, methods are known which are oriented on the production of tungsten oxide based on ore. Basically, such a process includes an alkaline roasting in order to convert the metals and carbides into corresponding oxides.CPC Scheme C01B NONMETALLIC ELEMENTS Binary compounds, i.e. compounds of nitrogen with only one other element chosen from metals, silicon, boron or carbon, are classified in groups C01B 21/06 or C01B 21/0605 C01B 21/076.Compounds of nitrogen with more than one element chosen from metals, silicon or boron are classified in C01B 21/0602 Documents relating to several specific binary compounds are classified in C01B 21/06 only and
