Calcium tungstate is a white crystalline with tetragonal system. It decomposes in hot hydrochloric acid. Also, it is slightly soluble in water and ammonium chloride solution. Its relative density is 6.062g/cm3, chemical formula is CaWO4, where W has a valence of +6. Producing Processes 1. Processed from natural scheelite. 2. Adopt tungsten trioxide and calcium carbonate as raw materials, and burn at the temperature of 1070°C. 3. Made by the reaction of calcium oxide/calcium hydroxide and tungsten oxide/tungsten hydroxide in…
