Abstract: The property of BaTiO3 nano powder prepared by the sol-gel method at different pH values was investigated.The effect of pH value on gel formation and aggregates was discussed with double electric layer theory and reaction mechanism.The optimal preparing condition of the powder was proposed (pH>8).

Key words: BaTiO3, sol-gel, pH value
