Tungsten trioxide powder may be used to produce a new type of functional glass, namely electrochromic glass, also known as smart glass, which can be said to be an energy efficient building glass. The reason why experts from all over the world began to study smart glass is mainly to solve the different requirements of glass heat insulation performance in different climate regions and different seasons.

Yellow tungsten oxide nanopowder is a type of nano functional material with excellent optical properties, and thus may be used for preparing an energy efficient building glass with high heat insulation and high heat preservation performance. As we all know, building energy efficiency is a huge project that requires everyone's joint efforts.

WO3 nanopowder may be used to produce an energy efficient building glass, which is a thermal insulation glass in hot summer and a heat preservation glass in cold winter. We all know that glass doors and windows have always been the focus and breakthrough for achieving the goal of building energy conservation. As people's decorative requirements for buildings continue to increase, glass is more and more widely applied in the construction industry.

Tungsten oxide nanopowder may be used to produce an energy efficient building glass. As is known to all, China is a big country with rapid economic growth and a population of 20% of the world. It is also a big country with relatively scarce energy. It has become the world's third largest energy producer and the second largest energy consumer.
