Violet Tungsten Oxide
Introduction
Name: Violet Tungsten Oxide
Formula: WO2.72
Abbreviation: VTO
Property
Violet tungsten oxide (WO 2.72 ), abbreviated as VTO, a tungsten oxide, purple finely crystalline powder, which the raw material ammonium paratungstate decides its particle size.
Preparation and Application
It comes from the production process of ammonium paratungstate by precisely controlling the temperature in the reduction state, mainly for the production of fine tungsten metal powder and tungsten carbide powder.
Property
TVO powder has maximum in the pore volume, and smallest in the pore volume, narrowest pore size distribution, the smallest fractal dimension and the largest average pore diameter, which advantage to the hydrogen reduction of ultrafine tungsten powder, but disadvantage to the doping process; the tungsten oxide has a unique crystal structure, which is particularly suitable for the production of fine tungsten powder and tungsten carbide powder.
