Single crystals of gamma -Li3PO4 have been grown from flux. The 4 X 8 X 9-m
m crystals have the cleavage along the [010] and [120] directions. The anis
otropy in ionic conductivity in the grown crystals, ((sigma parallel to a)/
(sigma parallel to b) = 2.5 and (sigma parallel to a)/(sigma parallel to c)
= 1.3), is explained by specific features of the gamma -Li3PO4 structure.
