Tungsten oxide can be said to be a transparent thermal insulation nanopowder. That is because the heat-insulating materials prepared using tungsten oxide nanoparticles as raw materials such as heat-insulating coating and heat-insulating film are highly transparent heat insulating materials. And these heat insulation materials can all achieve the thermal insulation purpose by shielding the radiant heat of the infrared light portion of the sunlight. The radiant heat of infrared rays accounts for nearly 50% of the total energy of sunlight.

Tungsten oxide nanopowder may be applied for producing a building glass energy saving coating. Why do these transparent architectural glasses need to be coated with a layer of tungsten oxide thermal insulation coating?

WO3 nanopowder may be applied for manufacturing a building glass energy saving coating. And the obtained heat insulation coating has good spectral selectivity. In other words, such coating has high permeability in the visible light region, and can effectively shield the heat radiation in the infrared light region.

Tungsten trioxide nanopowder may be applied for preparing a building glass energy saving coating. The coating consists of inorganic nanoparticles, namely tungsten oxide heat insulating particles, and a transparent resin.
