Synthesis and properties

The ZnTiO₃, Zn₂TiO₄ and Zn₂Ti₃O₈ forms crystallize in hexagonal, cubic (inverse spinel) and cubic structures, respectively. They can be produced by heating a mixture of ZnO and TiO₂ powders or processing it with a ball mill. Zn₂Ti₃O₈ forms at lowest temperatures, followed by ZnTiO₃ and then Zn₂TiO₄; the last phase dominates at temperatures above 1000 °C.
