Performance: suitable for evaporation of electron gun, film densification and stability. Excellent material for ultraviolet band. Does not dissolve in water, resistant to chemical properties, but at high temperatures can react with the hydroxide, the film is hard;

Application: it is mainly used in the ultraviolet film, anti - Anti - film or high - back - film and fire - resistant material, UV - near - infrared multilayer film.

HfO2 thin film is a kind of insulating oxide, can make the film resistance, but also can be used as a film, the general use of sputtering deposition.
