Gadolinium oxide (Gd2O3) from Sejin Sy Corp. is a white rare earth oxide supplied as a powder, with high neutron absorption capability and strong paramagnetic properties. It is used in MRI contrast agents, phosphors, nuclear reactor shielding, and optical glass manufacturing. This supplier offers it in industrial, high-purity, and electronic grades, packaged under moisture-free conditions in sealed drums or bags.
The material is a key intermediate in gadolinium metal production and advanced material synthesis, with typical particle sizes ranging from 1 to 10 micrometers depending on the grade. Standard purity levels for high-purity Gd2O3 exceed 99.9%, while industrial grades may range between 95% and 99%. Its density is typically 7.407 g/cm³, and it remains stable under normal storage conditions, though it absorbs moisture and CO₂ from the air over time.
Industrial buyers source this product for applications in nuclear energy, medical imaging, and specialty glass manufacturing. Sejin Sy Corp. trades internationally, with gadolinium oxide commonly shipped in 25 kg or 50 kg sealed containers. Buyers should confirm packaging, handling, and compliance with local regulations for rare earth materials before placing orders.
