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…
