Violet Tungsten Oxide

Violet tungsten oxide its phase component is WO2.72 (or W18O49), which is in one of tungsten oxide, abbreviated as VTO, is a finely crystalline powder purple, the color is generally rendered purple or blue-purple. It is under the precise control of temperature reduction state to APT as raw reaction in an argon atmosphere, and then the purple tungsten oxide oxygen, made purple tungsten. Purple tungsten tungsten oxide has several other different forms and structures with other tungsten oxide, it is a strong octahedral structure, showing the natural crystalline needle and rod form a bridge between each other, the particle distribution is more loose, its surface area, the average size and bulk density is smaller than blue tungsten, oxide and yellow tungsten oxide. So the performance of violet tungsten oxide has a big difference with others. However also because of its unique structure, so when preparation fine tungsten powder and tungsten carbide fine powder it has many advantages such as production speed and fine-grained and so on. So the violet tungsten oxide is widely used in science and technology and industrial areas.Its main composition and physical characteristics are as follows:
