Piezo Kinetics PKI 552 Lead Zirconate Titanate Piezoelectric
Categories:	Ceramic; Oxide; Titanium Oxide; Zirconium Oxide; Piezoelectric
Material Notes:	Denoted as Navy Type VI, this ceramic is used as sensors that require extremely high dielectric constant and large displacements. PKI 556 material has been slightly modified to give a higher g33 value, higher k33 , and lower loss factor. This formulation aids the design engineer by giving more flexibility within the type VI class of materials. Elastic Compliance s₁₁^E (x 10^-12 m²/n): 15.9. Elastic Compliance s₃₃^E (x 10^-12 m²/n): 20.2. Property data at 25°C. Information supplied by Piezo Kinetics, Inc.
Key Words:	PKI 552, PZT, Lead Zirconium Titanate; PbZrO3 - PbTiO3 Solid Solution; Oxides
