專利摘要 A method of fabricating barium titanate powders uses titanium tetrachloride and barium hydroxide as reactants in a reaction solution. The pH value of the reaction solution is adjusted to strongly alkaline range by adding potassium hydroxide. Nitrogen is charged into a reaction tank at normal pressure, and the reaction solution is heated at 80-102°. The solution is intensively stirred at constant temperature, and then subjected to a hydro-thermal reflux. Then, the solution is treated through an ion exchange resin and dried to obtain a cubic BaTiO 3 powders.
