Abstract
Syntheses of the homologous compounds InFeO3(ZnO)m (m = integer) in the In2O3-ZnFe2O4-ZnO system at 1150-1550°C are investigated. In FeO3(ZnO)m phases (m = 1-5 and 7) are stable above 1150°C. Single crystals of InFeO3(ZnO)m (m = 1, 2, 3, 7, 11, 13, 15, and 19) are grown by means of solid state reactions in mixtures of In2O3, Fe2O3, and ZnO powders, and crystals of Fe2O3(ZnO)m (m = 8 and 9) are grown from mixtures of Fe2O3 and ZnO powders at 1500 or 1550°C. The crystal data determined by means of a Weissenberg camera are as follows: InFeO3(ZnO): a = 3.32 Å and c = 26.1 Å; InFeO3(ZnO)2: a = 3.31 Å and c = 22.6 Å; InFeO3(ZnO)3: a = 3.30 Å and c = 41.8 Å; InFeO3(ZnO)7: a = 3.27 Å and c = 73 Å; InFeO3(ZnO)11: a = 3.27 Å and c = 104 Å; InFeO3(ZnO)13: a = 3.27 Å and c = 120 Å; InFeO1(ZnO)l9: a = 3.27 Å and c = 167 Å; and Fe2O3(ZnO)9; monoclinic crystal system with a = 5.60 Å, b = 68.1 Å, c = 29.5 Å, β = 94.2°. and C2/m space group. The crystal data determined by means of a single crystal X-ray diffractometer are as follows: InFeO3(ZnO)15: a = 3.267 Å and c = 135 Å; and Fe2O3(ZnO)8: orthorhombic crystal system with a = 5.5987(4) Å b = 68.358(7) Å, c = 53.67(4) Å, and Ccmm space group. InFeO3(ZnO)m belongs to R3̄m for m = odd or P 63/mmc for m = even and their lattice constants are given in a hexagonal form. The crystal data for InFeO3(ZnO)m and Fe2O3(ZnO)m are discussed based upon a wurtzite-type crystal structure.
