As you may have known, the ammonium metatungstate powder is a white or yellow, slightly acidic crystalline powder, which is soluble in water and insoluble in alcohol. Specifically, the molecular formula of ammonium metatungstate is H8N2O4W; the chemical formula is (NH4)6H2W12O40.XH2O; the molecular weight is 283.9145; the CB number is CB41411564; the EC number is 234-364-9; the CAS number is 14311-52-5; solubility (water) is 300g/100ml; the content of tungsten in ammonium metatungstate is 72%; the valence of tungsten in ammonium metatungstate is +6. And ammonium metatungstate has no harmful components. In other words, it will not pollute the environment. According to experts, the prepared cesium tungsten bronze is also environmentally friendly, so the obtained heat insulation material is also a green product.
