Abstract: The properties of three PZT-based piezoelectric ceramics and one PLZT electrostrictive ceramic were measured as a function of temperature. In this work, the dielectric, ferroelectric polarization versus electric field, and piezoelectric properties of PZT-4, PZT-5A, PZT-5H, and PLZT-9/65/35 were measured over a temperature range of-150 to 250 o C. In addition to these measurements, the relative thermal expansion of each composition was measured from 25 to 600 o C, and the modulus of rupture of each material was measured at room temperature. This report describes the experimental results and compares and contrasts the properties of these materials with respect to their applicability to intelligent aerospace systems. Keywords: piezoelectric, PZT, PLZT, temperature Introduction The term piezoelectricity refers to the relationship between pressure and electricity that exists within a unique family of materials. Piezoelectrics are materials that either output a voltage when subjected t...
