Additional work on dielectrics includes deposition of silica, PABS (lead aluminum boron silicates), PLZT (lead lanthanum zirconium titanate) and BST (barium strontium titanate) on Si-Ti-Pt wafers (Figure 2). The wafer specimens were patterned with metal electrodes and electronic properties were characterized.

Lead is poisonous, so that in addition to controlling the lead loss, the evaporated lead must be contained. In practice, this is achieved by surrounding the sample with lead-based powder compositions (31), such as a mixture of PbO and PbZrOs for lead-lanthanum-zirconium titanate (PLZT), to provide a positive vapor pressure in a closed AI2O3 crucible (Fig. 12.22). With the controlled atmosphere apparatus, PLZT can be sintered to full density (Fig. 12.23), yielding materials with a high degree of transparency. 

Lead hydroxy metal hydrazine carboxylate hydrates decompose exothermically to carbonate hydrazine intermediate, followed by an exotherm to form respective oxides such as lead zirconium titanate (PZT) and lead lanthanum zirconium titanate PLZT, as one can see from Figure 4.4. 

A wide array of ferroelectric, piezoelectric and pyroelectric materials have titanium, zirconium and zinc metal cations as part of their elemental composition Many electrical materials based on titanium oxide (titanates) and zirconium oxide (zirconates) are known to have structures based on perovskite-type oxide lattices Barium titanate, BaTiOs and a diverse compositional range of PZT materials (lead zirconate titanates, Pb Zr Tij-yOs) and PLZT materials (lead lanthanum zirconate titanates, PbxLai-xZryTii-yOs) are among these perovskite-type electrical materials.
