As a type of transparent thermal insulation nanopowder, the ding of blue tungsten oxide powder is mainly manifested in the production of transparent heat-insulating film. And this type of thermal insulation film has high visible light transmittance and good ultraviolet and near-infrared shielding characteristics. And therefore, it has a wide application in thermal insulation material such as building thermal insulation glass (window, door, and curtain wall, etc.) and auto window film.
Effect of APT on the Morphology of Blue Tungsten Oxide
The process of hydrogen reduction of raw material APT to blue tungsten oxide undergoes dehydration, deamination, and phase transformation processes. During the process, a large amount of water vapor and ammonia gas are discharged from the inside of APT particles. Due to the combined effects of gas evolution and phase transformation, a large number of cracks are generated in the APT particles, and the flower-like agglomerated particles are cracked and dispersed.
