Piezo products manufactured
for the most varied Piezo applications we have produced
more than 100,000,000 ceramic parts
Johnson Matthey has a tremendous experience to select the right piezo ceramic composition for the specified application. We select a suitable composition, by this each Piezo Actuator or Piezo Sensor will obtain the required electrical and mechanical properties.
Whether small-scale or large-scale production is chosen will depend on the requirements relating to the type of Piezo ceramic and the demand, so some kinds we produce continually based on constant demand.
In general there are two different manufacturing processes available for the production of the Piezo ceramics, depending on the desired piezo ceramics shapes, sizes and properties.
- pressing technique - ceramic powder is compressed before sintering.
- tape casting - the ceramic mass as a liquid (slurry) is casted onto a moving belt and dried, before sintering.
Both manufacturing processes are continuously in operation at Johnson Matthey Piezo Products.
Johnson Matthey offers piezo ceramic materials from a few pieces up-to high mass production quantities in rectangular and polygonal shapes:
- bare or
- metallized, polarized and tested.
