Properties and applications of nano-yttrium oxide

Nano yttrium oxide is rare earth oxide, appearance is white or white slightly yellow powder, cubic crystal.

Yttrium oxide chemical formula is Y2O3, molecular weight 225.81, density 5.01g/cm3, melting point 2410 ℃, boiling point 4300 ℃,

Good thermal stability, good physical and chemical stability, with good corrosion resistance. Insoluble in water and alkali, soluble in acid.

It is easy to absorb carbon dioxide and water when exposed to air, so it should be kept closed to prevent deterioration. With high corrosion resistance and high temperature stability, good stability to reducing medium, high dielectric constant .

High thermal conductivity, at 300K thermal conductivity up to 27W/(m... K), is about 2 times of Yttrium aluminum garnet (Y3Al5O12) crystal thermal conductivity, high thermal conductivity for its laser working medium is very favorable;

The optical transparency range is wide (0.29~8μm), and the theoretical transmittance can reach more than 80% in the visible region. The phonon energy is low, and the peak of Raman spectrum is 377cm-1, which is conducive to reducing the probability of non-radiative transition and improving the upconversion luminescence efficiency.
