Cesium tungstate for preparing near-infrared absorption film is also known as cesium tungsten bronze with the formula of CsxWO3. And it is often Cs0.33WO3 or Cs0.32WO3. It is reported that the near-infrared absorption film prepared using cesium tungstate nanoparticles as functional material is often used for heat insulation of building glass to reduce room temperature, thereby reduce energy consumption for air conditioning and thus decrease emission of carbon dioxide.

Nano tungsten trioxide for producing glass dome thermal insulating glass coating is a new type of environmentally-friendly energy saving material. The transparent coating film of such a coating formed on the glass can shield most of the ultraviolet rays and a large part of the infrared rays. And more than 70% of visible light can pass through the glass. In other words, the thermal insulation effect of the tungsten trioxide coating is significant without affecting the daylighting. In this regard, some experts have studied the ultraviolet-visible-infrared transmission spectrum of nano ATO/WO3/LaB6 composite systems, which has better thermal insulation performance than WO3 coating.

Nano tungsten trioxide for French window thermal insulating glass coating is a new type of high-tech environmentally-friendly nano material with excellent heat insulation and high visible light transmittance. Among them, the raw material nano tungsten trioxide needs to be made into a transparent heat insulating dispersion before being used to produce the French window thermal insulating glass coating.

Nano tungsten trioxide for office thermal insulating glass coating is a nano thermal insulation material with excellent heat shielding performance and high transparency. For example, some experts use ATO/WO3/LaB6 composite nanomaterials as heat insulation agents to prepare thermal insulating glass coating that can shield all ultraviolet rays and near infrared rays.
