It was observed that the annealing of porosity and structure defects in the near surface layers of the porous titania film (anatase) was enhanced on heating in oxygen in comparison to the heating in argon. ETA results were compared with SEM micrographs and XRD patterns of the titania film samples heated to 500 and 800degreesC, respectively. A mathematical model was used for the evaluation of the temperature dependence of the titania films microstructure development.
