Cesium tungsten bronze, a type of environmentally friendly functional material, is regarded as the best raw material for the preparation of nano heat insulating coating currently. Among them, the obtained coating is highly transparent heat insulation glass coating. You know, the glass coating industry originated in the late 1990s. It appeared as there is demand for energy conservation in China.

Cesium tungsten bronze has photochromic properties and electrochromic properties. In addition, it also has an important property --- selective transmission of spectrum, such as near-infrared shielding properties, so it is often used to prepare a new type of explosion-proof heat insulation coating, which is environmental friendly for applying to energy saving reconstruction of building.

Cesium tungsten bronze for producing heat-insulating anti-explosion coating has high light absorption performance in the near-infrared region. Specifically, the expert obtained cesium tungsten bronze powder by a preparation method in which the obtained powder had an absorbance at a wavelength of 928 nm in the near-infrared region of 1.41 and a minimum absorbance at a wavelength of 437 nm.

Cesium tungsten bronze for preparing French window thermal insulating film is a tungsten bronze type functional compound, which can be prepared by hydrothermal method --- an important method in the solvent chemical reduction method. Among them, the low temperature hydrothermal method is commonly used as it is simple and practical. However, experts said that low-temperature hydrothermal synthesis of tungsten bronze must solve two problems.
