Typical applications are protection of aluminum and silver mirror coatings, intermediate layer in wide band visible AR coatings and for XeCl (308 nm) laser AR and dielectric mirror designs. ... It is used as a coating in metal production. Yttria is often used with zirconia to form Yttria Stabilized Zirconia (YSZ).
Yttrium is a metal and oxygen a non-metal - because non-metals tend to gain and metals tend to lose electrons, metals typically react with non-metals by transferring electrons between them and forming ionic compounds ('salts')
Yttrium oxide (Y2O3) nanoparticle is an air-stable, solid substance white in color. It is used in the field of material sciences, to make phosphors that are used in imparting the red color of the picture tubes in televisions. Another major use of the yttrium oxide nanoparticles is in inorganic synthesis.
