Abstract
New sodium super ionic conductor (NASICON) type niobium aluminum phosphates of composition Cu0.5NbAlP3O12 (CNP) and HNbAlP3O12 (HNP) are prepared. The compounds are isomorphous with NbTiP3O12 and unit cell parameters are eval uated. Copper and hydrogen occupy the channels. Reduction of CNP gives rise to HNP. electron spin resonance (ESR) and photo acoustic (PA) spectral dat a are consistent with elongated octahedral configuration around Cu2+ ion.
