Lead(II) titanate is an inorganic compound with the chemical formula PbTiO3.
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[ZrxT1−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[clarify].
