Low acoustic impedance
PZT
Type Pz39
Microstructure of Pz39 at a magnification of 5000 times
01 Description
02 Key features and benefits
•
•
•
Lowest batch to batch variation in the industry
Stable material with consistent performance
Customised or standard designs
The new Ferroperm Pz39 material is developed primarily
with the aim of having very low acoustic impedance
and at the same time high permittivity and thickness
coupling coefficient. It has furthermore no oil or
polymer infiltration, and is therefore able to operate at
higher temperatures than traditional lead-
metaniobates.
•
•
High thickness coupling coefficient
High permittivity
Pz39 in combination with Pz36 and Pz37 therefore offers
a complete choice of materials for NDT transducers
and for other applications, where the acoustic
matching is critical.
03 Applications
Repeatable performance

NDT transducers
The main focus through our entire production process is to
provide materials and components with the highest
possible reproducibility of properties and parameters and
to obtain the lowest aging rates in the industry.
Medical transducers
Underwater transducers
Low frequency Doppler flow-meters
Our materials have a variation of ±5% for all parameters.
This reduces the requirements for impedance matching,
frequency tuning and dimensioning of the housing
meaning fewer rejects and lower costs.
