Zinc titanate, also known as zinc titanium oxide, is an inorganic compound existing in three major forms: ZnTiO<sub>3</sub> (ZnO-TiO<sub>2</sub>), Zn<sub>2</sub>TiO<sub>4</sub> (2ZnO-TiO<sub>2</sub>) and Zn<sub>2</sub>Ti<sub>3</sub>O<sub>8</sub> (2ZnO-3TiO<sub>2</sub>). It is used as a regenerable catalyst, a pigment and a sorbent of sulfur compounds at elevated temperatures. It is a white powder that is insoluble in water.
The ZnTiO<sub>3</sub>, Zn<sub>2</sub>TiO<sub>4</sub> and Zn<sub>2</sub>Ti<sub>3</sub>O<sub>8</sub> forms crystallize in hexagonal, cubic (inverse spinel) and cubic structures, respectively. They can be produced by heating a mixture of ZnO and TiO<sub>2</sub> powders or processing it with a ball mill. Zn<sub>2</sub>Ti<sub>3</sub>O<sub>8</sub> forms at lowest temperatures, followed by ZnTiO<sub>3</sub> and then Zn<sub>2</sub>TiO<sub>4</sub>; the last phase dominates at temperatures above 1000 ðC.
