Lanthanum silicate apatites are attracting due to their considerable interest as an electrolyte of solid oxide fuel cells. In this paper, we reported synthesis of two Bi-doped apatites and one undoped one. Apatite were synthesized by hydrothermal at 200 ºC for 3 days from La2O3, Na2SiO3, and Bi2O3(for Bi-doped). Le Bail refinement of X-ray data showed that all apatites have a hexagonal cell (P 63/m space group). The lattice parameters of La9.5Bi0.5Si6O27 and La9Bi1Si6O27 are a = b = 9.718(1) Å, c = 7.190(1) Å, and a = b = 9.724(1) Å, c = 7.189(1) Å, r. There is increase in lattice parameters with increasing content of Bi.
