Abstract Paratellurite crystals grown by the Czochralski technique often contain Pt inclusions unless extrapure source material is used. Using analytical data obtained on comparable uniform paratellurite crystal samples we have shown that there is a joint incorporation of Pt and the added Fe. In the absence of Fe in the melt no incorporation of Pt occurs. The undesirable interactions of Pt inclusions with dislocations are pointed out.

Abstract The Miyazawa hypothesis [J. Crystal Growth 49 (1980) 515] on the gas-bubble entrapment in Czochralski grown paratellurite is criticized and complemented. To avoid gas-bubbles, instead of applying a concave growing surface, the use of extrapure raw material is proposed.
