Tungsten oxide nanoparticles may be used to prepare thermal insulation dispersion liquid, and then be applied to produce thermal insulation films or thermal insulation coatings. These heat insulating materials all have the advantages of high heat insulation, energy conservation, environmental protection and high ultraviolet resistance, so they have a wider application in architectural glass or automotive glass. With the promotion and application of downstream heat insulation products, tungsten oxide is also becoming more and more known to people. For example, solvothermal preparation of tungsten oxide nano particles has received considerable attention.

So, what is solvothermal method? The solvothermal method was first used by mineralogists in the laboratory to study the mineral formation process under supercritical conditions. Later, this method was widely used in the synthesis of molecular sieves and other crystalline materials. Solvothermal synthesis refers to the synthesis under the thermal conditions of organic solvents. Its application in the preparation of inorganic materials has been developed in the past 30 years. Hydrothermal and solvothermal synthesis methods have been developed in recent years, and their application in inorganic materials is also becoming increasingly mature.
