Piezoelectric Staves

CeramTec is a leader in the design and manufacture of complex piezoelectric ceramic components and assemblies used in a wide range of applications and cutting edge technologies.


Applications include
    Features
    • Choice of metallisation (Silver, Nickel, Gold and others)
    • Evaporated and chemically deposited metallisation's available
    • Thickness/Radial frequency tuning available on request
    • Wrap around electrode configuration
    • Wide choice of piezoceramic formulations
    Typical Stave Configurations

    Barrel

    Wedge

    Other custom stave design in combination with electrode configurations and metallisation’s are available on request.

    Dimensional Range

    Barrel Design

    • Outside Diameter from 8mm (0.3”) to 150mm (5.9”)
    • Inside Diameter from 6mm (0.24”) to 140mm (5.5”)
    • Length from 1mm (0.039”) to 150mm (5.9”)

    Stave Design

    • Length from 1mm (0.039”) to 150 (5.9”)
    • Width from 8mm (0.3”) to 25.4mm (1”)
    • Thickness from 5mm (0.2”) to 25.4mm (1”)

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


    Standard Mechanical Tolerances
    • Outside Diameter (*) ± 0.150mm
    • Inside Diameter (*) ± 0.150mm
    • Length (**) ± 0.05mm
    • Width (**) ± 0.150mm
    • Thickness (**) ± 0.05mm
    • Angle ± 0.25°

    Tighter mechanical tolerances are achievable but are dependent on the ring inside and outside diameters and thickness.

    Notes: (*) Barrel design, (**) Wedge design


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