Abstract

The congruent melting composition of strontium barium niobate has been investigated over the ternary composition region by DTA, X-ray fluorescence, Curie temperature and lattice parameter measurements. The composition of congruent melt was found to be close tox=0.61,y=0.4993 for the formula (Srx Ba1−xO)1−y. (Nb2O5)y. Striation-free single crystals are grown from the melt with this composition. The conceivable reasons for the discrepancy between the results of this work and the previous data are briefly discussed.
