PZN Ceramics

 

 

PZN ceramics have high coefficients of electrostrictive and dielectric constants. They are used in the production of hydrophones, actuators, receivers, projectors, sonar transducers, integrated layered capacitors, and micro-positioning devices. PZN is an abbreviation for Pb(Zn1/3 Nb2/3)O3, a chemical compound which includes lead (Pb), zinc (Zn) and niobium (Nb). PZN also forms solid-solution alloys with lead titanate (PZN-PT) and barium titanate (PZN-BT).

PZN ceramics are zinc-modified lead niobate compositions that exhibit an electrostrictive or relaxor behavior where strain varies non-linearly (quadratically). By defintion, relaxor materials exhibit a high dielectric constant over a range of temperature during transition from ferroelectric to paraelectric phase. The temperature corresponding to maximum dielectric constant is dependent on frequency. Relaxor crystal actuators can produce strain levels in excess of 1% and exhibit five times the strain energy density of conventional piezoceramics.
