Tungsten oxide nanopowder may be used to prepare an energy saving glass coating, which is a new type of environmentally friendly heat insulation coating. In the National Eleventh Five-Year Development Plan, the requirement for building energy efficiency is to achieve the goal of saving 60% of energy. As up to 70% of the building's thermal energy is lost from the glass doors and windows, people are paying more attention to the energy-saving of building glass, and glass heat insulation coating as well.

WO3 nanopowder may be used to prepare a transparent energy saving glass coating, which has excellent heat preservation and heat insulation effect, so it can reduce the use of air conditioning in hot summer and the use of heating equipment in cold winter, thereby reducing building energy consumption.

Tungsten trioxide nanopowder may be used to prepare an environmentally friendly energy saving glass coating. According to statistics, the annual output of glass in China is about 13.44 million square meters, of which more than 80% is used for architectural decoration. As of the end of 2004, China’s existing building glasses is about 1.5 billion square meters. With so many glass buildings, it also brings huge energy consumption. So, how to reduce the energy loss of glass doors and windows?

Nano yellow tungsten oxide may be used to prepare a multifunctional coating, namely an energy saving glass coating. The prepared coating is a thermal insulation coating and a new environmentally friendly coating.
