Lead(II) titanate is an inorganic compound with the chemical formula PbTiO3. It is the lead salt of titanic acid. Lead(II) titanate is a yellow powder that is insoluble in water.

At high temperatures, lead titanate adopts a cubic perovskite structure. At 760 K,[2] the material undergoes a second order phase transition to a tetragonal perovskite structure which exhibits ferroelectricity. Lead titanate is one of the end members of the lead zirconate titanate (Pb[ZrxTi1-x]O3 0xpiezoelectric ceramics; PbTiO3 has a high ratio of k33 to kp with a high kt.

Lead titanate occurs in nature as mineral macedonite.[3][4]


Lead titanate is toxic, like other lead compounds. It irritates skin, mucous membranes and eyes. It may also cause harm to unborn babies and might have effects on fertility.[5]

Solubility in water

The solubility of hydrothermally-synthesized perovskite-phase PbTiO3 in water was experimentally determined at 25 and 80 °C to depend on pH and vary from 4.9x10-4 mol/kg at pH?3, to 1.9x10-4 mol/kg at pH?7.7, to "undetectable" (<3.2x10-7 mol/kg) in the range 10<pH<11. At still higher pH values, the solubility increased again. The solubility was apparently incongruent and was quantified as the analytical concentration of Pb.[6]
