Title: The reactivities of TiO2 (rutile and anatase) for the solid-state reactions with BaSO4 and BaCO3
Abstract: DTA and isothermal kinetic studies were carried out on the reactions of BaSO4 or BaCO3 with TiO2 (anatase and rutile) to BaTiO3. In the initial steps, the reactions of BaSO4 with TiO2 (anatase) proceeded to BaTi4O9, of BaSO4 with TiO2 (rutile) to BaTi3O7, and of BaCO3 with TiO2 (anatase and rutile) to Ba2TiO4, respectively. These reactions were connected with the formation of binary metal oxide through some intermediates, which are BaSO4 or BaCO3 incorporated with TiO2. The reactivity of anatase was higher than that of rutile in all reaction systems.
