Nano Cs0.33WO3, or cesium tungsten bronze nano powder, may be used to prepare a new transparent heat insulation coating. As you may have known, there are many types of transparent heat-insulating coatings on the market. And there are mostly tin antimony oxide (ATO), indium tin oxide (ITO), and zinc aluminum oxide (ZAO), etc. However, these functional materials are expensive. And their resources are scarce. And therefore the prices of theses coatings are higher.

Nano Cs0.33WO3, nano grain size cesium tungsten bronze, may be applied to prepare a type of transparent thermal insulation coating. And the nano cesium tungsten bronze can be produced by hydrothermal synthesis using Na2WO4•2H2O and Cs2CO3 as raw materials, and citric acid as an inducer.

Nano Cs0.33WO3, cesium tungsten bronze nanoparticles, may be applied for producing near-infrared shielding material, such as, heat-insulating film, and therefore be used in building glass. According to experts, the nano particle size cesium tungsten bronze raw material is a nano material that has many special properties, such as, surface and interface effects, quantum size effects, small size effects, macroscopic quantum tunneling effects, and the like. The reason why nano cesium tungsten bronze has these properties is that it has special structure.

Nano Cs0.33WO3, or nano grain size cesium tungsten bronze, may be applied for preparing a transparent thermal insulation paper. In fact, the obtained thin paper can be said to be an environmentally friendly heat-insulating film, which is more and more widely used in building glass. According to experts, they prepared the raw material cesium tungsten bronze nano particles by high-temperature solid-phase reaction method, and studied its transmission spectrum.
