Abstract
The crystallization behavior and electrical properties of a piezoelectric glass-ceramic system consisting of lead titanate (PT) or lead zirconate titanate (PZT) in a lead borosilicate matrix is presented. Glass powders of compositions in this system densify at 650°C, and crystallize the ferroelectric PT or PZT phases. 60Pb(Zr0.52Ti0.48)O3.20PbO.20SiO2 is provided as an example of a composition that when pressed from a glass powder and heat treated to 850°C produces piezoelectric d33 and g33 coefficients of 23 pC/N and 43×10−3 Vm/N, respectively. Results are also presented for a previously developed PT based glass-ceramic for comparsion.
