Abstract

Lanthanum silicate apatite with various concentration of Bi-doped of La10-xBixSi6O27 were successfully synthesized by hydrothermal method in order to study effect of Bi-doped tp its structure and conductivity properties. It is found that main peaks of lanthanum silicate apatite were observed with amount of impurities. The value of conductivity at 500°C determining from AC impedance measurement was in the range between 1.99 × 10-6 S/cm and 2.03 × 10-6 S/cm. The highest conductivity was observed in the sample with x = 0.5, 1.0 and 1.5.
