Abstract
The phase diagram of the La2O3-Ta2O5-Ga2O3 system around La3Ta0.5Ga5.5O14 ( LTG) was investigated by a differential thermal analysis and the quenching method. La3Ta0.5Ga5.5O14 single crystals were subsequently grown from diffe rent starting melt compositions using the Czochralski technique. The effect of the starting melt composition on crystal quality was examined by measur ing the variation in the chemical composition and lattice parameters along the growth axis. On the basis of these experimental results, we have grown LTG single crystals over 2 inches in diameter. (C) 2001 Kluwer Academic Pub lishers.
