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 720 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 0≤x≤1, PZT) system, which is technologically one of most important ferroelectric ceramics.
[edit] Toxicity
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.[3]
