Nanometer blue tungsten oxide may be applied for preparing transparent thermal insulation material and therefore be applied in the heat insulation fields of construction and automotive. The blue tungsten oxide can be obtained by the self-reduction preparation process of ammonium paratungstate. In other words, it is the process of self-reduction of the cracked product of APT at high temperature by using APT to crack H2 at high temperature.
The process adopts traditional equipment. By rationally configuring the process parameters and controlling the self-reduction process parameters, various performance indexes of blue tungsten oxide can be controlled. And the production process is easy to control, so that the industrial production is realized. Through self-reduction method, the blue tungsten oxide can be successfully produced by rationally formulating the process parameters, which not only saves cost but also reduces environmental pollution. On the basis of economic benefits, the preparation process has also achieved great benefits in environmental protection and safety, and realized the organic combination of safety benefits, environmental benefits, economic benefits and social benefits, which is worthy of promotion and application.
