ABSTRACT OF THE DISCLOSURE A method for manufacturing fine powders of lead titanate which includes the steps of reacting a water-soluble titanium compound or the hydrolysis product of a titanium compound with a lead compound in an aqueous alkaline solution having a pH value not less than 11.2, at a temperature not less than 100°C to obtain a precipitate of lead titanate fine powder, and then recovering the lead titanate fine powder from the remaining solution. By adjusting the pH and the synthesis temperature at proper values, it is possible to synthesize different forms of lead titanate, including a perovskite structure, a pyrochlore structure, or acicular (needle-like) crystals with a novel crystal phase. The acicular fine lead titanate crystals have an X-ray diffraction peak at 2.theta.=30.71° using a copper target.
