Our HPZ Materials
Ionix has invented a series of proprietary high-performance ferroelectric, piezoelectric materials (HPZTM) which enable devices that can serve a range of demanding environment applications. Our ability to tailor materials optimised for high temperature, high strength and radiation resistance, makes for a versatile technology that is readily manufactured using conventional ceramic production techniques.
Product Performance
Current Piezo (PZT)
- 200 – 250 degrees C
- High sensitivity lost above temperature limit
- Small movement/ stroke
- Highly brittle, prone to mechanical failure
Ionix HPZ
- Up to 600 degrees C
- High sensitivity retained
- 4 x higher movement
- Finer features
- 3 – 4 x stronger
- Reduced failure
- Higher Max Temperature
- Higher strain
- Less brittle
Ionix is building on established piezo technology.
The high-performance properties of our ceramics means they are incredibly versatile and can be used for a wide range of applications.
Product Range
HPZ380
The flagship product for high temperature piezoelectrics, HPZ380, is based on Ionix proprietary ceramic composition.
With a higher piezoelectric activity than other materials at these operating temperatures, HPZ380 meets the requirements of the most demanding applications.
Why use HPZ380?
- Long term operation at 380 °C
- High piezoelectric activity (d33) compared to competitor materials
- High mechanical strength and toughness

HPZ Ceramics FAQ
Yes. HPZ operates in a similar way to PZT and can be utilised using the same control methods. At lower operating temperatures (below 150 C), PZT may be preferable for price sensitive applications where PZT is already suitable, however the unique properties of HPZ can offer advantages even at lower temperatures. We will be happy to discuss your application and advise suitability.
HPZ is currently used in a variety of different applications, such as structural health monitoring (HotSense), flow monitoring, power ultrasound and valve actuation. If you have an application which you think might benefit from HPZ materials, fill in the contact form and our ceramics team will be happy to discuss this with you.
HPZ exhibits a unique combination of high piezoelectric activity and high operating temperature. HPZ operates at temperatures higher than traditional PZT materials, whilst exhibiting higher activity than other high temperature piezoelectrics.
Ionix have developed solutions for bonding HPZ to a variety of materials, such as 300 series stainless steels and titanium, for operation at high temperature. Ionix have also developed HPC, a high temperature piezoelectric composite, for conformal coating of complex geometries.
