Blue tungsten oxide powder, also known as WO2.92, may be used to produce thermal insulation thin film and can be applied to prepare ultrafine tungsten powder under appropriate process conditions. As you may have known, tungsten carbide, as an important tool material and structural material, plays a significant role in many fields with the development of science and technology. However, it is a brittle material. And there is a contradiction between its hardness and strength. Conventional WC-based tungsten carbide tool materials cannot meet the needs of modern industrial development, so it requires the development of fine-grained tungsten carbide with high hardness, high strength and high wear resistance.
The main raw material of fine-grained tungsten carbide is fine tungsten powder, so the particle size and uniformity of tungsten powder become the key to prepare submicron tungsten carbide. Therefore, the production of ultrafine tungsten powder has placed increasing demands on tungsten oxide raw materials, especially in terms of purity and uniformity of raw materials. At this time, researchers found that blue tungsten oxide powder is very suitable for the preparation of ultrafine tungsten powder. After that, blue tungsten oxide is widely applied to produce tungsten power.
