Cerium Oxide (CeO₂) Micron Powder – High Purity, -325 Mesh
Ultra-Fine Ceria Powder for Precision Polishing, Glass Finishing, and Advanced Industrial Applications
Product Description
Cerium Oxide (CeO₂) Micron Powder is a high-purity rare earth oxide with a particle size of -325 mesh and a minimum purity of 99.99%. This fine, white powder is widely recognized for its excellent polishing capabilities, particularly in glass, optics, and semiconductor industries. As a rare earth compound with a cubic face-centered crystal structure, cerium oxide exhibits unique redox behavior, high thermal stability, and significant oxygen storage capacity, making it valuable for catalysis and electronics.
Its strong hardness (Mohs 6) and high melting point (2600 °C) allow it to withstand extreme conditions in both chemical and mechanical applications. Cerium oxide is also known as ceria, and it’s favored for precision lapping, glass polishing, and chemical-mechanical planarization (CMP) in microelectronics.
