Ultrafine Grain Size Violet Tungsten Oxide 189

Ultrafine grain size violet tungsten oxide may be prepared by different production processes. At present, violet tungsten oxide (VTO) is generally produced by using ammonium paratungstate (APT) as raw material, and calcining APT with the injection of ammonia gas (NH3) in a rotary furnace. However, the VTO powder prepared by this method has large particle size and high impurity content, that is, it is difficult to obtain VTO powder with higher purity. Research also shows that a method for preparing…
