Hexagonal apatite type La_<9.33>(SiO_4)_6O_2 and La_<9.7> Si_6O_<26.55> single crystals as an oxide ionic conductor have been successfully prepared by the sintering method, and an anisotropy in their conductivities was confirmed. The conductivity component parallel to the c-axis was 10-100 times higher than the perpendicular component.

用烧结法成功地制备了六方磷灰石型La_<9.33>（SiO_4）_6O_2和La_<9.7>Si_6O_2<26.55>单晶，并证实了它们的电导率各向异性。平行于c轴的电导率分量比垂直分量高10-100倍。
