Ionic Conductivity of Ln10(SiO4)6O3 (Ln = La, Nd, Sm, Gd and Dy)
Electrical properties were investigated for lanthanoid-silicates of Ln10(SiO4)6O3(Ln = La, Nd, Sm, Gd and Nd). The conductivity at 773 K was 2.3 × 104 S cm−1 for Nd10(SiO4)6O3. The sole carrier is the O2− ion, which was determined using an O2 gas concentration cell.
