The microstructure of an a-TiO2:ZnO system obtained by two different synthesis techniques is investigated. Equimolar a-TiO2:ZnO is subjected to high-energy planetary ball milling as a dry mechanical technique and a solvothermal method as a wet technique for preparing zinc titanates. The investigation is performed by XRD and HR-TEM. The mechanical route results in the formation of ZnTiO3 as a major product accompanied by Zn2Ti3O8 as a minor one. The solvothermal route results in the formation of Zn2Ti3O8 accompanied by traces of zincite. The thermal stability of later zinc titanate is explored under different temperatures and results in a homogeneous amorphous nanocrystalline phase transformation without a compositional change.
