Tungsten Trioxide Applied for Office Thermal Insulating Film

Tungsten trioxide can be prepared into an electrochromic film. And when such a film is applied to the glass curtain walls of office. It is an office thermal insulating film. Well, how to synthesize the raw material - tungsten trioxide nanoparticles?

According to the experts, the tungsten trioxide nanoparticles can be synthesized from a tungsten wire by plasma generated in water by 2.45 GHz microwaves. The method allows control of the nanoparticle size and shape and the optical properties through pressure alone without any additives. For example, the spherical tungsten trioxide nano particles with a peak diameter of 7 nm were synthesized from a tungsten wire with a diameter of 1 mm by 200 W at 20 kPa at a high production rate of 4 mg/s. Whereas, rhombic cylindrical nanoparticles together with spherical nanoparticles were synthesized with a peak diameter of 13 nm at 101 kPa. In addition, plasma and bubble behavior was observed by high-speed camera. Use of a plate to control the updraft of the bubbles caused the gap between the plate and the coaxial electrode to remain consistently filled with bubbles, and plasma generation continued without pause.
