The nano-sized BaTiO3:La3+ powders were prepared by sol-gel process using butyl phthalate, barium acetate and lanthanum oxide as raw material, and these samples were tested by means of TG-DTA, XRD and SEM. The results indicate that with the annealing temperature and the doped concentration rising, the powders’ particle sizes will increase and decrease respectively. When annealing temperature is 900℃and doped concentration is 7%, the phase is cubic without other phases, and the particle size of power is 43 .34 nm.
