What Is Purple Tungsten Oxide?
Purple tungsten oxide (WO2.72 or W18O49, Purple Tungsten Oxide or Violet Tungsten Oxide, VTO for short) is a kind of tungsten oxide, which is a purple finely divided crystal powder with a molecular weight of 227.36.
Physical And Chemical Properties Of Purple Tungsten Oxide:
Appearance: purple or blue-purple broken crystal powder
Solubility: Insoluble in water, alcohol and most acids, soluble in ammonia and lye.
Preparation method of purple tungsten oxide:
The preparation of violet tungsten oxide is usually produced by controlling certain reducing conditions using ammonium paratungstate (APT), tungstic acid or tungsten trioxide (WO3) as raw materials. The preparation methods of violet tungsten usually include APT wet hydrogen direct reduction method, hydrogen tungstate reduction method, and APT mild reduction method.
Uses of purple tungsten oxide:
