Tungsten Trioxide Applied for Bedroom Thermal Insulating Glass Coating

Tungsten trioxide for preparing bedroom thermal insulating glass coating is tungsten trioxide nanopowder, more specifically, metal oxide nanopowder, which can be produced by using a chemical method - the sol-gel technique. And the sol-gel method is known as a very simple and inexpensive approach in which shape and size of powder can successfully be controlled.

According to the experts, this method is known as a simple approach for preparing metal oxide powders where polymeric precursors are made from metal salts, ethylene glycol, and citric acid during a low-temperature heat treatment. The main advantage of this approach is that metal ions are often mixed in atomic level, resulting in an increase in reaction rate. In this method of powder preparation, two reactions occur: at first complex formation between citric acid and metals, and subsequently esterification between citric acid and ethylene glycol (EG). As a result, the polymeric organic net formed by the esterification reaction decreases the ion segregation.
