Porous ceramics powders expected to have wide applications from catalytic to electronics. However, it is difficulty to maintain the pores up to high temperature. This work tries to study the possibility of producing porous oxides powder with thermal stability. Porous TiO2-P2O5 nanocomposite powders have been synthesized by sol-gel method in the presence of tri-block copolymer (EO)20(PO)70(EO)20 (Pluronic123). The TiO2 nanocrystals with a diameter of 3.6 nm precipitated in the as-synthesized materials in the presence of surfactant at 80°C considerably lower than those for traditional heat-treatment in the solid state, the nanocrystal was anatase but maintained the same size upon calcinations in the temperature range of 400-500°C.
