Nano grain size tungsten trioxide is a type of transparent thermal insulation nanopowder. It is said to be transparent, mainly to describe the state it exhibits when it is applied in the form of thermal insulation film. Thanks to its own photochromic performance, this type of thermal insulation material may shield UV and near infrared rays, which are the main reasons of "hot" in hot summer.
The thermal insulation nanopowder may finally be applied in the thermal insulation glass of building (office, and home, etc.), which will reduce room temperature, decrease energy charge and improve human comfort.
Besides, tungsten trioxide also has electrochromic performance and gasochromic performance, so that it has great application prospects in the following fields, such as optical information storage, light control, optical switches, optical device materials, optical information genetic materials, large-area screens, "smart windows", anti-glare rear mirrors, hydrogen sensors, and so on. And therefore, it has received much attention.
