Dark blue nano tungsten oxide may be applied for producing thermal insulation thin film, which can also be used to prepare metal tungsten powder. As you may have known, tungsten oxide and reduction conditions determine the grain size of tungsten powder, and the grain size of tungsten powder largely determines the final grain size of tungsten carbide powder. Since tungstic acid and tungsten trioxide are replaced with blue tungsten oxide in the late 1980s and early 1990s, the quality and…

Blue tungsten oxide nano powder may be applied for producing thermal insulating glass material, which is widely used in fields requiring high heat insulation and high transparency, such as buildings, automobiles, and the like. Strictly speaking, the blue tungsten oxide powder mentioned above is not the same as the industrial blue tungsten oxide. Industrial blue tungsten oxide is a powdery mixture of various tungsten compounds, that is, it is an industrially unclear product whose chemical composition and physical structure are…

Blue tungsten oxide nanopowder not only may be applied for preparing thermal insulating glass material, but also can be used as a raw material for the production of ultrafine tungsten powder. In the preparation of tungsten powder, if the process conditions are controlled, it is advantageous for the preparation of fine or ultrafine tungsten powder.
