Nanometer blue tungsten oxide may be applied for preparing thermal insulation dispersion liquid. The obtained dispersion liquid has the characteristics of uniform particle size and high crystallinity. Such dispersion liquid also has super-dispersion property, so that it is easily dispersed in various polar or non-polar organic solvents and water. And therefore it is used for applications such as heat insulating glass.
Blue tungsten oxide can also be used to prepare tungsten powder. There are many factors affecting the performance of tungsten powder. The main ones are the tungsten powder production process and the raw materials used. For example, the production of ultrafine tungsten powder should use tungsten oxide raw materials with lower oxygen content, while the preparation of coarse tungsten powder should select tungsten oxide raw materials with higher oxygen content. Therefore, the preparation process of blue tungsten oxide has attracted the attention of the majority of tungsten powder technology workers for lower cost, lower environment pollution, higher performance, higher efficiency and higher safety.
