WO3 is a photochromic material, so WO3-TiO2-ZnO composite film is also a photochromic material with excellent photochromic properties. Well, do you know how to prepare WO3-TiO2-ZnO composite film?

Yellow tungsten oxide is applied as a cement-based absorbing material because it has certain shielding properties against gamma rays. Well, what is the shielding performance of yellow tungsten oxide against gamma rays? Some experts used tungsten oxide powder as a fine aggregate to prepare a sample of φ10.5cm x 6cm cylindrical cement-based materials, and tested the shielding performance of the sample against gamma rays through an experimental system composed of a PTW UNDOS standard meter and ~ (60) Co, ~ (137) Cs sources.

ZnO-WO3 composite film is a composite thin film inlaid with ZnO nanocrystals. More specifically, the composite film adopts amorphous WO3 as a matrix, and ZnO nanocrystals are uniformly distributed in the amorphous tungsten oxide. Some experts have prepared ZnO-WO3 composite film on aluminum foil by sol-gel method, and its modification has been carried out with activated carbon. Taking methyl orange aqueous as simulated organic pollutant, photocatalytic degradation performance of ZnO-WO3 films is studied.

Tungsten carbide cutter is specially designed with an upper cutter and a lower cutter for applying to mask making machine. According to the experts, the quality of tungsten carbide upper and lower cutters is affected by many factors. Wherein, the change of various process parameters during the sintering process has a great impact on the quality of the cutter. And the performance of cutter is determined by the materials such as the binder and the base material. Besides, the cleanliness of the particle surface and particle size also affect cutter’s performance.
