Abstract
Relations between the growth conditions and macroscopic defects have been investigated for paratellurite (TeO2) crystals. Formation of gas bubbles, which are often found in the crystals, is due to the effect of the melt-flow and can be prevented by the slow pulling rate (about 1.5 mm/hr) combined with proper rate of the seed rotation. Subgrain structure (lineage) can be eliminated by selecting the [110] axis as the pulling direction.Keywords
