Tungsten Oxide Powder Applied for Thermal Insulating Glass

Tungsten oxide powder may be applied in the field of thermal insulating glass. And tungsten oxide may also be used in the field of electrochromic devices. As an electrochromic device, it is necessary to consider the response time of tungsten oxide. At the same time, the diffusion coefficient of hydrogen ions should also be considered.tungsten oxide powder applied for thermal insulating glass picture
Some researchers have used cellulose membranes with pore size of 50nm and 100nm to filter suspension containing tungsten oxide nanocrystals respectively, and thereby nanocrystalline tungsten oxide film is obtained. Samples with different discoloration properties were obtained by controlling parameters such as annealing temperature, number of crystal grains, and grain size of tungsten oxide. These samples are analyzed and compared to found that the densely distributed porous tungsten oxide obtained by annealing the larger size nanocrystals (100nm) at 400°C has the shortest response time and the diffusion coefficient of hydrogen ions is as high as 10-7cm2/s.
