Abstract
Crystals of KTiOAsO4 were grown by the high temperature solution method and their optical and ionic conductivity properties evaluated. The band edge and IR cutoff were 370 and 4850 nm, respectively. A domain structure prevented efficient frequency conversion in as-grown crystals. The ionic conductivity at 22 °C and 120 kHz was 1.5×10−8, 7.3×10−9, and 1.7×10−6 S/cm for the [100], [010], and [001], respectively. The alleged ferroelectric Curie temperature was 852 ±2 °C.Keywords
