Method for producing lead zirconate titanate polycrystalline ceramics |
| abstract |
A combination of critical calcining and firing conditions together with control of particle size of the calcined material and control of the harmful impurities SiO2 and Al2O3 enables processing of polycrystalline ceramic bodies of lead zirconate titanate (PZT) containing about 1 percent Nb2O5 to densities of at least 99.7 percent of theoretical density. In addition, such PZT bodies exhibit a radial coupling coefficient greater than 60 percent. Applications include use as a piezoelectric element in microphone transducers. |
