Near-infrared Shielding Material: Cs0.33WO3

Cs0.33WO3, as the most widely studied near-infrared shielding material, is attracting more attention from different fields including nano materials, energy saving buildings and heat insulation products for autos. Well, you know, there are many other heat insulation materials such as LaB6, ITO and ATO. How about the heat insulation effects of Cs0.33WO3, LaB6, ITO and ATO?

It is reported that much less amount of LaB6 or Cs0.33WO3 is found to provide the same level of solar shielding effect or to obtain the same shading coefficient (per unit projected area through the film) compared to ITO and ATO. It means that Cs0.33WO3 has better heat insulation performance than ITO and ATO. Then, what is shading coefficient? Shading coefficient is defined as the ratio of the solar energy flowing into a vehicle or a room through an object to the solar energy which passes through 3 mm thick clear float glass. Thus, smaller shading coefficient provides better solar-control effect.
