Yttrium oxide (Y2O3) nanoparticle Reference
- Metal oxide nanoparticles demonstrate uniqueness in various technical applications due to their suitable physiochemical properties. In particular, yttrium oxide (Y2O3) nanoparticle is familiar for technical applications because of its higher dielectric constant and thermal stability. It is widely used as a host material for a variety of rare-earth dopants, biological imaging, and photodynamic therapies.
It is mined in China and Malaysia. Yttrium also occurs in the other ‘rare earth’ minerals, monazite and bastnaesite. Yttrium metal is produced by reducing yttrium fluoride with calcium metal.
Examples of oxides of ceramics include Al2O3, ZrO2, SiO2, aluminum silicate, magnesia, and other metal oxide-based compounds. These are categorized as inorganic, nonmetallic compounds because they contain oxygen, carbon, or nitrogen.
Yttrium oxide (Y2O3), commonly known as yttria, is a technologically important refractory ceramic material useful for a large number of applications. It has a high melting point (2410°C), shows chemical inertness, and hence is used as corrosion-resistant coating.
