| Abstract: | Barium titanate fine powders were prepared by sol precipitation process.The effect of concentration of NaOH solution as precipitator on phase composition was investigated,and the reaction mechanism of pure barium titanate fine powders prepared by sol precipitation process was proposed.Wet gels after washing with distilled water were treated with surface active agent or/and organic solvent.By surface modification,agglomeration was well controlled,and properties of powder were greatly improved. |

| Keywords: | fine barium titanate powder sol precipitation process preparation characteristics |
