摘要

We presented the conductivity, X-ray diffraction and Na-23 NMR spectra of Cu1-yNa0.2+yZr1.9Mg0.1 (PO4)(3) with Na and Cu mixed ions defined as ionic ratio i = [Na]/{[Na] + [Cu]}. Lattice parameters a axis decreased linearly with increasing ionic ratio and c axis increased linearly with increasing ionic ratio. Conductivity against ionic ratio showed a minimum around i = 0.8. NMR spectra of Na-23 nucleus showed a strong quadrupole interaction. The quadrupole coupling constant showed an anomaly around i = 0.8. We observed new results on the mixed ion effect.
