Application
Gadolinium(III) oxide is used as a dopant in zirconia to improve the ionic conductivity of solid electrolytes in solid oxide fuel cells. Its presence enhances the performance and efficiency of these energy conversion devices. It is also used as a component in thermal barrier coatings for gas turbine engines and other high-temperature applications. Its thermal stability and low thermal conductivity make it suitable for protecting components from extreme heat.
General description
Gadolinium(III) oxide is a rare-earth oxide known for its high thermal stability and unique magnetic properties, making it valuable in various high-temperature applications. It is widely used as a host material in solid-state lasers, where doping with rare-earth ions like neodymium or erbium enhances laser efficiency and enables specific wavelengths for telecommunications and medical procedures3. Additionally, its nanoparticles are utilized in biomedical imaging as MRI contrast agents due to their excellent biocompatibility and ability to improve image resolution.
