Abstract: The In 2 O 3 -SnO 2 -ZnO system is important for the transparent conducting oxides . The isothermal phase diagrams of the ternary In 2 O 3 -SnO 2 -ZnO system at 1400 and 1500 °C were experimentally studied by quenching experiments followed by XRD and EPMA phase analysis. A new ternary In 2 Sn 2 Zn 2 O 9 phase with crystal structure analogous to R3c ZnSnO 3 was found, and its eutectoid decomposition reaction to In 2 O 3 bixbyite s.s. + Zn 2 SnO 4 spinel s.s. + SnO 2 was determined to be 1310 ± 10 °C. In addition, a small homogeneity range of this ternary phase toward In 2 O 3 was found: In 2+2x Sn 2-x Zn 2-x O 9 where x = 0.0 ∼ 0.2 by Zn 2+ + Sn 4+ = 2 In 3+ substitution.
