Thermo Fisher, 010822.A1, Niobium(V) oxide, Puratronic™, 99.9985% (metals basis)

Thermo Scientific Chemicals Niobium(V) Oxide Puratronic is high-purity niobium pentoxide powder for optical, electronic and advanced ceramic materials development. The material has formula Nb2O5, CAS 1313-96-8 and molecular weight 265.81 g/mol. Its stated purity is 99.9985% on a metals basis, with total metal impurities no higher than 15 ppm and tantalum limited to 10 ppm. Supplied as a 1 kg quantity, this grade provides a high-purity oxide feedstock for studies involving niobium-based ceramics, dielectric materials and the synthesis of compounds such as lithium niobate. In research on optical waveguides, piezoelectric systems and oxide electronics, trace impurities may influence material properties and process repeatability. Protect the powder from cross-contamination during handling and select synthesis or sintering conditions appropriate to the desired final phase.
