VIOLET TUNGSTEN OXIDE

Violet tungsten oxide is manufactured under a certain reduction condition from the raw materials of ammonium paratungstate (APT), tungstic acid or tungsten trioxide (WO 3). The preparation methods of violet tungsten oxide are mainly APT wet hydrogen direct reduction, tungstic acid hydrogen reduction and APT mild reduction method ect... Violet tungsten oxide shorted for VTO, chemical formula is WO2.72 or W18O49, prepared by APT wet hydrogen reduction, tungstic acid hydrogen reduction and APT mild reduction method, mainly used for manufacturing tungsten powder and tungsten carbide powder.
