The phase stability and phase transition temperature of three nano-oxides Al{sub 2}O{sub 3}, TiO{sub 2} and Fe{sub 2}O{sub 3} are thermodynamically determined by considering effects of surface energy and internal pressure induced by surface stress on the total Gibbs free energy. The established model corresponds to available experimental and simulation results of Al{sub 2}O{sub 3}, TiO{sub 2} and Fe{sub 2}O{sub 3} nanocrystals.
