Violet tungsten oxide nanopowder is one of the important raw materials for the preparation of heat-insulation glass coating. Due to its excellent optical properties and environmental protection, this environmentally friendly thermal insulation coating is increasingly used on architectural glass. Therefore, everyone began to pay attention to the use of raw material tungsten oxide in the field of heat insulation. And some of them are also concerned about the preparation of raw material powder - W18O49.

Violet tungsten oxide nanopowder may be used to prepare thermal insulation dispersion, and the obtained transparent dispersion is combined with fluorocarbon resin to prepare nano transparent heat insulating glass coating with high transparency, high adhesion, high hardness, excellent water resistance and good alkali resistance, in line with the national standards. The visible light transmittance of the coated glass reaches 75%, and the coating film reduces the temperature of the hot box by 6°C.

Violet tungsten oxide nanopowder is an important raw material for preparing water-based thermal insulation dispersion, and the obtained dispersion together with aqueous fluorine-containing resin can be used for preparing an environmentally-friendly nano transparent thermal insulation coating. So, why choose a water-based fluororesin instead of any other water-based resin to prepare tungsten oxide heat insulation coating?

Violet tungsten oxide nanoparticles for building glass energy saving coating can be prepared by chemical precipitation method. Specifically, some experts have used a chemical precipitation method to prepare a reduced phase tungsten oxide powder with a crystal phase and a chemical composition of W18O49. The method is divided into two steps:
