Noliac manufactures piezoceramic materials based on modified lead zirconate titanate (PZT) of high quality for custom specifications. Piezoceramic materials are usually divided into two groups: hard doped and soft doped materials.
Hard doped PZT can be exposed to high electrical and mechanical stresses. The stability of their properties makes them ideal for high-power applications.
These are Noliac’s standard hard doped piezo materials currently available – click for specifications.
* For multilayer components only
Piezoelectric materials NCE41 and NCE40 are low loss materials for high power applications. The low dielectric and mechanical losses (tan(δ), Qm) combined with high piezoelectric charge constant (d33) make them suitable for high-performance ultrasonic applications.
Furthermore NCE41 and NCE40 can be exposed to high repetitive quasi-static and dynamic loads for ignition applications. NCE41 and NCE40 differ from each other in permittivity and mechanical quality factor values.
The piezoceramic material NCE80 is intended for power transducers with highest electric drive. Its low dielectric and mechanical losses at extremely high electric drive and high coupling factors make it suitable for high-power applications.
Soft doped piezoceramic materials have their strength in applications requiring high strain. The high sensitivity of the materials make them particularly suitable for sensing applications, receivers, actuators and low power transducers.

These materials are characterized by high relative permittivity, large electromechanical coupling factors, large piezoelectric constants and low mechanical quality factors. They are distinguished by a comparatively high domain mobility and thus “ferroelectrically soft” behaviour, i.e. relatively easy polarization.
Piezoelectric materials NCE51 and NCE57 are standard soft materials, particularly suitable for actuators and low power nonresonant applications in which high coupling factor and /or high charge sensitivity are requested.
Piezoceramic material NCE53 has slightly lower electro-mechanical coupling factor, but has the advantage of higher temperature stability, and it is suitable especially for shear mode vibration sensors.
Piezoelectric materials NCE55 and NCE56 are very high sensitivity materials featuring extremely high permittivity, large coupling factor and piezoelectric constant. These materials are suitable for a wide range of high sensitivity applications.
