Piezoelectric Plates & Bars

CeramTec is a leader in the design and manufacture of complex electronic ceramic components and assemblies used in a wide range of applications and cutting edge technologies. CeramTec Industrial specialises in the development and production of piezoceramic plates and bars, for which a wide range of metallisation variants is possible.

Features
  • Choice of metallisation (Silver, Nickel, Gold and others)
  • Evaporated and chemically deposited metallisation's available
  • Thickness frequency tuning available on request
  • Wide choice of piezoceramic formulations

CeramTec manufactures piezoelectric ceramic blocks designed for use in ultra-low SONAR applications up to 18KHz. These blocks (Navy II material standard) offer excellent electrical characteristics, exhibit high sintering density and are available in nine high-sensitivity piezoceramic formulations suitable for the fabrication of wide bandwidth composite transducers (1-3 composites). However, the most striking feature of the PZT ceramic blocks is their size and especially their thickness, which is currently a maximum of 48 mm.

Typical Electrode Configurations

Other custom electrode configurations and metallisation’s are available on request.

Dimensional Range
  • Length from 0.25mm (0.01”) to 165mm (6.5”)
  • Width from 0.25mm (0.01”) to 165mm (6.5”)
  • Thickness from 0.15mm (0.006”) to 48mm (1.9”)

Custom sizes dimensions outside of the above may be possible – please consult for further information.


Standard Mechanical Tolerances
  • Length & Width ± 0.150mm
  • Thickness ± 0.05mm
  • Squareness (edge to face): Within 0.15°
  • Flatness (lapped parts): 0.012mm (lapped), 0.015mm (sliced)
  • Parallelism: 0.012mm (lapped), 0.06mm (sliced)

Tighter mechanical tolerances are achievable but are dependent on the plate length, width and thickness.


Metallisation Type
  • Silver fired thick film
  • Evaporated nickel
  • Electroless nickel - Gold flash
  • Tin - Evaporated Gold and others available on request
