Abstract
Crystals of potassium titanyl arsenate were prepared by top seeded solution growth from a tungstate flux. X-ray
topography revealed extensive growth banding in several sectors, associated with temperature induced fluctuations in
composition and impurity content. This was confirmed to some extent by energy dispersive X-ray analysis
measurements which revealed significant levels of tungsten incorporation from the flux and higher levels of iron
impurity from the starting materials. The overall dislocation density in (0 1 1) and (0 0 1) growth sectors was determined
to be 5102 cm�2. X-ray diffraction rocking curve measurements confirmed a low average strain across the crystal.
