摘要：

A pseudo-binary phase diagram between the perovskite Pb(Mg 1 3Nb 2 3)O3 and PbO has been established by D.T.A.. The melting point of PMN was found at 1320°C and the eutectic temperature at 830±2°C with the eutectic composition of 74%PbO 26%PMN (in wt%). On the basis of the determined phase diagram single crystals of the perovskite phase have been grown by the high temperature solution technique by using 30wt% PbO as solvent. The obtained crystals show pseudo-cubic form with (100)cub. growth steps or degenerated forms. Size (∼ 1cm) and quality of the obtained crystals are adequate for physical characterizations. © 1990.
