Tungsten Trioxide Applied for Hotel Heat Insulating Glass Coating

Tungsten trioxide for preparing hotel heat insulating glass coating is a heat shielding material. Wherein, the tungsten trioxide powder is often doped with a group I A or II A metal and halogen. The experts introduced a method for manufacturing such a heat shielding material, and the manufacturing steps are shown as follows.

Step One: Provide a tungsten trioxide precursor solution containing a group VIII B metal element.
Step Two: Dry the tungsten trioxide precursor solution to form a dried tungsten trioxide precursor.
Step Three: Subject the dried tungsten trioxide precursor to a reducing gas at a temperature of 100 °C to 500 °C to form a composite tungsten trioxide. The heat shielding material includes composite tungsten oxide doped with a group I A or II A metal and halogen, represented by MxWOy or MxWOyAz, wherein M refers to at least one of a group I A or II A metal, W refers to tungsten, O refers to oxygen, and A refers to a halogen element. The heat shielding material also includes a group VIII B metal element.
