摘要：

Single crystal of hexagonal apatite type Nd-9.33 (SiO4)(6)O-2 which is an oxide ionic conductor was prepared by the FZ method and an anisotropy of its conductivity was investigated. The conductivity of a parallel component to a c-axis (2.1 x 10(-8) S cm(-1) at 30 degrees C) was higher about one order of magnitude, compared with that of perpendicular component.
