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[ Zrx T1−x] O3, 0 ≤ x ≤ 1, PZT) system, which is technologically one of the most important ferroelectric and piezoelectric 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]
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]
