Single crystals of NaSb3F10 have been grown from solution by a slow-ev
aporation technique at constant temperature (305 K). The grown crystal
s were confirmed by chemical and X-ray analyses. The electrical conduc
tivity studies of NaSb3F10 have been carried out in the temperature ra
nge from 30 to 190-degrees-C. The dielectric constant (epsilon) and di
electric loss (tan delta) were determined as a function of frequency i
n the range from 100 Hz to 100 kHz and in the temperature range from 3
0 to 190-degrees-C. The values of epsilon11 and epsilon13 for NaSb3F10
at 100 kHz are about 14 and 19 respectively.
