Dark blue nano tungsten oxide not only can be applied for the manufacturing of infrared thermal insulation nano material, but also be used to prepare medium grain size tungsten powder by cyclic redox process.
As you may know, tungsten carbides may crack or break during use. Studies have shown that most of the places where tungsten carbides appear cracks and fractures are large-sized crystal grains. That is to say, in the production process, it is necessary to control the appearance of large-sized crystal grains in tungsten carbide. As most of large-sized grains in tungsten carbide are caused by coarse particles in tungsten powder, if you want to minimize or eliminate large-sized crystal grains in the tungsten carbide to improve its performance, it is necessary to reduce or eliminate coarse particles in the tungsten powder during the preparation process of tungsten powder. Therefore, the cyclic redox method is used, which can help reduce or eliminate coarse particles in the tungsten powder, and provide raw material guarantee for the production of high-quality tungsten carbide.
