Application

Yttrium(III) oxide, typically found as a white powder or in sintered forms with a purity of 99.9%, serves multiple advanced applications due to its unique properties. It efficiently absorbs atmospheric CO2 and has an enthalpy of fusion of 105.00 kJ/mol. In its crucible form, yttrium oxide is essential for experimental and proprietary melting processes. The sintered pieces are crucial for creating evaporation materials used in hard film dielectric coatings and thin film capacitors. Additionally, yttrium oxide is available in various purities, such as 99.999%, 99.99%, and 99.9%, serving as a high-quality sputtering target for producing hard films and dielectric coatings. Its role extends to the synthesis of perovskite-type structures like YAlO3 with chrome ions, enhancing phase formation and sintering properties. Yttrium oxide is also a key component in manufacturing neodymium Nd:YAG lasers and in the components of MOS and LED transistors.
