Gadolinium Oxide (Gd2O3) Micron Powder

Purity: 99.99%, Size: 2-3 μm

Gadolinium Oxide (Gd2O3) Micron Powder is a highly specialized rare-earth inorganic compound characterized by its exceptional thermodynamic stability and unique paramagnetic properties. At a high purity level of 99.99%, this fine white powder exhibits a high refractive index and excellent thermal conductivity, making it a critical material in advanced materials science. Its crystal structure, typically cubic at room temperature, undergoes precise phase transitions at elevated temperatures, ensuring its integrity in high-heat environments. Beyond its physical robustness, the material is distinguished by having one of the highest thermal neutron capture cross-sections of any known element, a property that makes it indispensable in nuclear and radiation physics. Its ability to interact with magnetic fields at the atomic level, combined with its transparency in the visible spectrum when integrated into glass or ceramic matrices, positions it as a foundational component for next-generation optical and medical technologies.
