Purple tungsten Oxide Application

Purple tungsten oxide, was also known as TVO (purple tungsten oxide). It is not a chemical compound sense, but comprise different chemical composition, such as arsenic trioxide, tungsten, copper, and low levels of tungsten trioxide. The relative content of these compounds depends on the purple tungsten oxide calcination parameters. Xiamen Tungsten Online Technology Co., Ltd. produces two kind of purple tungsten oxide which has oxygen content content standards. Purple tungsten oxide is mainly used in the production of tungsten metal powder and tungsten carbide. Tungsten can also be used to produce ultra-fine powder and nano-tungsten powder. Purple tungsten and other tungsten oxide have large differences on the internal feature and structure. It is each particle by needle or rod grains loose particles group, which has a great gap grain structure, low bulk density, this structure is conducive to the reduction process of hydrogen and water vapor infiltration escape, therefore, suitable for the production of fine particles. Reduction obtained from purple tungsten and the tungsten powder fine and uniform particle dispersion between good so it is suitable for the preparation of an ultra-fine grain cemented carbide materials.
