Gadolinium oxide
Gd₂O₃ - Rare earth oxide for high-performance applications in medicine, optics and nuclear technology
Gadolinium oxide (Gd₂O₃) is a white to slightly pink-colored, stable compound of the rare earth metal gadolinium. Due to its unique magnetic properties, its neutron absorption and its high temperature resistance, it is used worldwide in demanding industrial applications. PROJECTOR supplies industrial customers with high-purity gadolinium oxide, packaged in batch units that are tailored to requirements and areas of application.
Typical areas of application for gadolinium oxide:
Gadolinium oxide plays a key role in medical technology, particularly as a base material for MRI contrast agents, where it serves as a paramagnetic agent for image enhancement in magnetic resonance imaging. In the ceramics industry, it is used to produce high-temperature resistant materials, while in nuclear technology its ability to absorb thermal neutrons is used - for example as a component of fuel elements. Another field of application is optoelectronics: here, gadolinium oxide is used as an additive in special glasses and phosphors, e.g. for plasma screens or fluorescent lamps. Thanks to its stability and compatibility with other lanthanide oxides, it is also suitable for the production of laser crystals and magnetic materials.
