Application Note

Thermo Scientific Chemicals Tantalum(V) Oxide Puratronic is a high-purity tantalum pentoxide powder for electronic-materials research, thin-film processing and advanced ceramics. Its chemical formula is Ta2O5, molecular weight is 441.89 g/mol and CAS number is 1314-61-0. The 500 g grade has 99.993% purity on a metals basis excluding niobium, with a maximum niobium impurity of 50 ppm and total metal impurities limited to 70 ppm. Tantalum pentoxide is valued for its dielectric properties and is investigated in capacitor structures, optical glass, thin films and resistive switching devices. The low trace-metal impurity level is useful when contamination can affect device behavior or material characterization. Suitable processing may involve thermal treatment, ceramic fabrication or thin-film deposition, depending on the experimental method. Control contamination during powder weighing, transfer and storage.
