摘 要:<正> In this paper,various techniques including BET,XRD,SEM and XPS were used to study the sintering ofpure and La2O3-doped titania.The experimental results show that sintering of titania proceeds via volume diffu-sion.Adding of lanthanum oxide decreases the rate of sintering and hinders the phase transition from anatase torutile crystal by strong surface interaction between the mixed crystals(La4Ti9O24,La0.66TiO2.99)and TiO2.
