Kinetic Model for TiO Polymorphic Transformation from ...


We propose a distribution kinetics model for the polymorphic transformation (anatase to rutile) and coarsening of TiO 2. Based on population balance equations for the size distributions of the dimorphs, the simplified model applies a first-order rate expression for transformation combined with Smoluchowski coalescence for coarsening of anatase and rutile particles. Two moments of the size ...

Review of the anatase to rutile phase transformation


Review of the anatase to rutile phase transformation ... initial crystalline TiO 2 phase formed is generally anatase [82, 83]. From a structural perspective, this could be due to the greater ease of the short-range ordered TiO 6 octahedra in arranging into long-range ordered anatase structure owing to the less-constrained molecular construction of anatase relative to rutile [84]. Alternatively ...
