Violet tungsten oxide may be used to prepare a transparent heat insulation film that may be applied to architectural glass or automotive glass to obtain heat-insulating energy-saving glass. As you may have known, there are many preparation methods for the raw material nano particle size violet tungsten oxide, such as, a microemulsion method, a chemical vapor deposition method, a hydrothermal synthesis method, a sol-gel method, and the like.

As different precursors, different preparation methods and preparation conditions will affect the morphology, structure and properties of nano grain size violet tungsten oxide. Therefore, it is very important to choose an appropriate preparation process to produce the violet tungsten oxide nano particles with ideal ratio and morphology. While the violet tungsten oxide nano powder with ideal ratio and morphology is the key to play the thermal insulation ding of the thermal insulation film. In other words, violet tungsten oxide nanopowder for producing energy-saving coating should have ideal ratio and morphology.
