APPLICATIONS
Light-emitting materials: Yttrium vanadate powder doped with rare earth elements (such as europium, dysprosium, etc.) is an important light-emitting material, which can be used in the manufacture of phosphors, cathode ray tubes, light-emitting diodes and other optoelectronic devices.
Laser materials: Nd:YVO₄ is a commonly used laser crystal with good optical and laser properties, which can be used to manufacture high-performance laser devices such as diode-pumped solid-state lasers.
Optical devices: Because yttrium vanadate has good optical transparency and refractive index uniformity in the ultraviolet to infrared wavelength bands, it can be used to manufacture passive devices for optical communication, such as optical isolators, circulators, rotators, delays, and polarizers.
Electronic ceramics: can be used as additives for electronic ceramics to improve the electrical and mechanical properties of ceramics, improve the sintering performance and densification of ceramics, so as to prepare high-performance electronic ceramic materials, such as capacitors, piezoelectric ceramics, thermistors and so on.
Catalyst: With certain catalytic activity, it can be used as catalyst for certain chemical reactions, such as organic synthesis reaction, catalytic oxidation reaction in environmental protection, etc. It helps to improve the reaction rate and selectivity, and reduce the reaction temperature and energy consumption.
