Our Manufacturing Facilities

Our production facility can produce a wide range of geometries of piezoelectric ceramic, including discs, plates and high-temperature shear bars. We also have the expertise and equipment required for multilayer actuator production and encapsulation. Ionix also developed a proprietary process for producing conformal piezoelectric coatings directly onto metal, and methods of bonding dissimilar materials, for use at elevated temperature.

Powder Production

Ionix manufacture a unique ceramic composition for extreme environments and have developed bespoke systems for client requirements.

Disc/Bar Manufacturing

We produce a wide range of standard discs and bars to enable your piezoelectric application.


The Ionix team can synthesise custom stacks for your high-temperature application.

Complex Geometries

The unique fracture toughness and temperature resilience of our materials allows complex geometries with fine details to be synthesised.

Integrating the Product

Raw Materials

Ceramics Components

Sub-component Manufacture

Sub-assembly Manufacture

Ionix have experience of manufacturing piezoelectrics, from ceramic production through to device construction, and can help tailor the properties of materials or components for your application. We have the flexibility to integrate into any stage of the supply chain and development of specialist components for various applications is part of our remit. The bonding and device production expertise developed by Ionix has been utilised to facilitate integration of piezoelectric components into a number of novel high temperature devices.
