Lead(II) titanate is an inorganic compound with the chemical formula PbTiO3. It is the lead salt of titanic acid and has a high ratio of k33 to kp with a high kt. 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, 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 0≤x≤1, PZT) system, which is technologically one of the most important ferroelectric ceramics.
