Single crystals of K-x(ZnyTi8-y)O-16 priderites have been grown from a melt of K2O-MoO3 using the flux-zone technique. High-purity crystals > 10 mm in length were obtained, with no indication of twinning. Lattice parameters of a=1.0162(8) nm and c=0.2971(7) nm were obtained from X-ray diffraction measurements. Habit planes were identified from scanning electron microscope images. X-ray photoelectron spectroscopy confirmed the titanium oxidation state as +4. High-temperature complex impedance spectroscopy between 300 and 820 K was used to electrically characterize the crystals. This indicated that the materials had a low d.c. conductivity and a conductivity of 1.68 x 10(-3) S cm(-1) at 100 kHz.
