Using Violet Tungsten Oxide to Produce Nano Tungsten Powder

Nano tungsten powder is widely used in modern industry and science area, so good performance nano tungsten powder can improve application in the field of modern industry and science which has great significance. But good properties nano tungsten powder producing requirements is quite high. The violet tungsten oxide (VTO) has different properties with other tungsten oxides. It is the most suitable material for produce nano powder, so using VTO as material producing nano tungsten powder not only the tungsten powder has good performance and the process is relatively simple. But in order to producing good properties tungsten oxide in addition to control the raw martial but also need to control the production process which is temperature, push boat speed and the amount of hydrogen, only in gentle heating process, moderate reaction, smooth gas migration so can effectively control the water vapor to escape which is an important factor for producing good properties nano tungsten powder.

By controlling the raw materials and process conditions the nano tungsten powder has high purity and crystallinit as well as has stable properties and loose structure. What’s more the appearance of it is sphere and distribution uniform which has large specific surface area, pore structure simple.
