Tungsten trioxide, as a new type of environmentally friendly dingal material, is regarded as the most suitable raw material for preparing bathroom heat insulating glass coating. Therefore, more and more scholars have begun to study this new thermal insulation material. For example, to study the question --- how to prepare tungsten trioxide powder with controlled crystal plane growth.

A Preparation Method for Controllable Growth of Crystal Surface of Tungsten Trioxide Crystal for Bathroom Heat Insulating Glass Coating
The commercial tungsten boride (WBx) without any treatment was used as a precursor, and it was placed in a reaction kettle filled with nitric acid aqueous solution. After the reaction kettle was sealed, it was placed in an oven and heated. Remove the reaction sample, and tungsten oxide crystals with (002) crystal plane dominance can be obtained in the nitric acid system by washing and drying with the deionized water. Or take tungsten boride as a precursor, put it into a reaction kettle filled with an ethanol solution of hydrofluoric acid. After the reaction kettle is sealed, put it in an oven to heat it. And then take out the reaction sample, wash it with deionized water and dry it. Finally, heat the dried sample in air to obtain tungsten trioxide crystals in the hydrofluoric acid system.
