Cadmium tungstate

Cadmium tungstate (CdWO ) is used in fluorescent paint, X-ray screens, and scintillation counters and as a catalyst. It is very toxic when inhaled. [Pg.145]

When mixed with caustic soda solution, cadmium oxide forms precipitate of cadmium hydroxide. Many insoluble cadmium salts are obtained by such precipitation reactions. For example, mixing aqueous solutions of cadmium nitrate with ammonium tungstate results in precipitation of cadmium tungstate. [Pg.152]

Cadmium Tungstates.—The anhydrous normal salt, CdWO, remains as colourless crystals when a mixture containing sodium tungstate (4 parts), sodium chloride (16 parts), and cadmium cliloride (11 parts) is heated to complete fusion and allowed to cool. The hydrate, CdW04.2H20, is formed by double decomposition. ... [Pg.215]

Alumina catalysts activated by additions of dehydrogenating catalysts, e.g., nickel oxide, copper oxide or sulfide, zinc oxide or sulfide, cobalt selenide, zinc phosphate, cadmium tungstate, mixtures of the oxides of zinc and tungsten, of cadmium and molybdenum, etc., are claimed to be superior in the formation of acetaldehyde from mixtures of steam and acetylene at 350° to 400° C.l-la Zinc oxide catalysts may be activated in a similar way by the addition of small amounts of molybdates or molybdic acid, and are effective at 300° to 350° C.121b... [Pg.238]

Modern CT systems use solid state detectors in general. Each detector element consists of a radiation-sensitive solid-state material (such as cadmium tungstate, gadolinium-oxide or gadolinium oxi-sulfide with suitable dopings), which converts the absorbed X-rays into vis-... [Pg.7]

Additionally, two cadmium chromates are known (classed with chromate pigments) along with a cadmium tungstate (classed with tungsten pigments). Lithopone forms - that is, pigments coprecipitated with barium sulfate (q.v.) - of the cadmium sulfides are also extant. The composition of cadmium white mentioned in later nineteenth cenmry literature is not well known Salter (1869) describes it as a hydrated oxide or carbonate of cadmium. [Pg.69]

Cadmium tungstate is probably of limited interest although according to the Colour Index (1971 Cl 77208) it is used in the USA in fluorescent paints. [Pg.72]
