Abstract

A pseudoternary phase diagram of the BaO-ZrO 2-ScO 1.5 system was established at 1600 °C, and solubility of scandia into barium zirconate was determined. According to the phase diagram, the solubility of scandia into barium zirconate at 1600 °C is 0.29 in a mole fraction of scandia ( X ScO1.5) on the composition line where the mole fraction of barium oxide is 0.50. However, the solubility of scandia into barium zirconate is reduced with decreasing temperature and lies in between X ScO1.5 = 0.10 and 0.20 at 1300 °C.
