Abstract
Peroxo-tantalic acid solution was obtained by direct reaction of Ta(OC2H5) with H2O2. It turned into amorphous Ta2O5· nH2O when dried. Thermal analysis revealed that Ta2O5·nH2O thus formed underwent three-step thermal decomposition. Final product up to 700°C was hexagonal tantalum oxide. Electrical conductivity of spin-coated Ta2O5·nH2O was measured with ac impedance method, revealing that temperature and humidity dependence of ionic conductivity (4.3×10-7 S cm-1 at 27°C) was very small.
