Tungsten Trioxide Applied for Living Room Thermal Insulating Glass Coating

Tungsten trioxide for the production of living room thermal insulating glass coating is nanostructured tungsten trioxide. It has been confirmed that nanostructured tungsten trioxide exhibits improved properties in comparison to the conventional coarse-grained structures. This is believed to result from the greatly increased surface area, which provides a large interface between the solid and a gaseous or liquid medium to react.

So, tungsten trioxide nano particles are receiving more attentions. And therefore the preparation of WO3 powder is paid much attention. There is something about the preparation of WO3 nanopowder. Many researchers have studied preparation of tungsten trioxide by sol-gel method. It is reported that nano WO3 powder with uniform size and spherical shape can be synthesized in the presence of oxalic acid and cetyltrimethylammonium bromide as the complexing and surface active agents, respectively. Results of the investigations revealed that the morphological characteristics of the powder like particle size and shape depend strongly on the preparation conditions such as nature of precursor, solvent, the surface modifier and quantities of them.
