Zirconia (ZrO2) Component Manufacturing
Small batch production of zirconia does depend on the geometry of the component. There are three general processing routes:
- Precision grind a general blank of zirconia
- Laser cut a zirconia substrate
- Injection moulding
For higher quantities, Zirconia (ZrO2) lends itself to the injection moulding process rather well. Expensive tooling is required but a high degree of dimensional accuracy can be achieved.
Laser cutting zirconia is also a relatively straight forward process. The limits on thickness that a laser can go through is typically 1mm. Zirconia (ZrO2) in this form is widely used throughout the electronics industry.

Unlike traditional ceramics that tend to be hard and brittle, Zirconia offers high strength, wear resistance, and flexibility far beyond those of most other technical ceramics.
Fracture Toughness
The ability to resist fracture is a mechanical property of materials known as fracture toughness. For advanced ceramics it uses a critical stress intensity factor known as KIC where the fracture normally occurs at the crack terminations.
