Yttrium oxide (Y203) is an important rare earth metal oxide with a variety of applications.
Basic properties
Yttrium oxide is a white or slightly yellow crystalline powder with a density of 5.01 g/cm³, a melting point of 2425°C, and a boiling point of 4300C. It is insoluble in water and alkali, but soluble in acid
Preparation method
Yttrium oxide can be prepared by a variety of methods, including sputtering, cold pressing and hot pressing. Sputtering uses argon ions to bombard yttrium oxide targets, sputtering the material on the surface of the target onto the substrate to form a thin film. The cold pressing sintering process is to cold press yttrium oxide powder at room temperature and then sinter it at high temperature, while the hot pressing sintering process is carried out under high temperature and high pressure conditions
Application areas
Optical materials: Used as an additive for optical glass to manufacture high-temperature transparent glass and infrared lens raw materials Electronic materials: Used in the electronics industry for film and capacitor materials with high dielectric constant Ceramic materials: Used to manufacture special ceramics and refractory materials
Phosphor: Used for high-brightness phosphors and other cathode ray tube coatings for large-screen TVs
Alloy additives: Used as additives in steel and non-ferrous alloys to enhance oxidation resistance and mechanical properties
Laser technology: Used as a bubble magnetic area material for high-pressure lasers and storage components.
