UprYZe™ ultra-tough ceramic  

UprYZe enables to the manufacturing of ultra-tough ceramic 

Ceramics are strong and hard materials that can resist both high temperature and very corrosive environments. The main constraint to use ceramics in some structural applications are their toughness and ability to withstand crack propagation.  

As all materials will eventually have defects, either from its manufacturing process or just by ageing, the objective for a tough ceramic is therefore to avoid cracks will induce a dramatic failure of the ceramic material.  

UprYZe™ is specifically developed to boost the toughness of technical ceramics and is suited for applications for which high mechanical performance and impact resistance are required. 

Stress resistance before and after pre-cracking the ceramic sample A ceramic with a higher toughness like 

UprYZe-Shock will resist a higher stress even if it contains small defects. 

For ceramic applications UprYZe from Zirpro have the best positioning in terms of toughness, strength and impact resistance, making them the material of choice for the most demanding applications.  

Properties include:

• Outstanding toughness (Kic = 15 MPa.m1/2) 

• Exceptional impact resistance (+50% vs. 3mol% Y-TZP). 

Performance of UprYZe is achieved with a standard sintering cycle (1450°C-2hrs in air), no special sintering is required (for example: HIP). 

¹ceramic obtained with Zirpro powders

Specifically tuned for structural and decorative ceramics

UprYZe-Shock is the original tough zirconia developed and patented by Zirpro. The performance achieves the status of one of the toughest ceramic materials available today, for use in welding pins and other industrial applications. 

UprYZe-Black was developed for consumer goods applications. Polished and high gloss colors enhance aesthetical and mechanical performance together with high toughness (similar to UprYZe-Shock).
