Outstanding Mechanical Performance
Among all ceramic oxide materials, tetragonal zirconia stabilized with the addition of 3mol% Y2O3 (Y-TZP) exhibits at room temperature the highest performance in terms of:
-
Bending strength
-
Toughness
-
-
Tetragonal zirconia also enables the manufacturing of ceramic parts with:
-
Excellent surface finishing
-
Superior wear resistance
-
Outstanding corrosion resistance
Saint-Gobain ZirPro offers world-leading 3mol% yttria-stabilized zirconia powders ranging from dry powder (CY3Z) suitable for injection molding or casting process to ready-to-press granules (GY3Z) used in uniaxial and isostatic pressing or even ready-to-mold feedstock for injection molding of complex parts. Please refer to Feedstock for Injection Molding page for more information.
Black pigmented zirconia for decorative fine ceramic applications is also available.
All ZirPro powders are manufactured using a state-of-the-art chemical process to ensure excellent performance and consistent high quality.

ZirPro has developed a CY3Z portfolio that enables to address all needs in terms of applications and ceramic processing:
- CY3Z-R grades (specific surface area of 7m²/g), are suitable for the manufacturing of advanced ceramic parts (grinding media, knives, cutting tools,) by injection molding or casting
- CY3Z-M (Specific surface area of 15m²/g) grades are suitable for the manufacturing of small size ceramic parts with very fine microstructure like Optical Fiber Connectors by Ceramic Injection Molding.
All of the powders are made using a state-of-the art chemical process, to ensure high purity (99,99%) and homogeneous sub-micronic particle size.

ZirPro offers 3 mol% yttria-stabilized zirconia ready-to-press granules (GY3Z-R60) that exhibit
- High purity (99.9%)
- Fine and homogeneous particle size
- Advanced binder system
GY3Z-R60 allows the manufacturing of ceramic parts with outstanding mechanical performance.
ZirPro ready-to-press granules are used in advanced technical ceramics thanks to its excellent mechanical performance, excellent pressing ability and green machining.

Thanks to the coupling of Zirconia and Alumina, ColorYZe-Arctic White offers enhanced mechanical performances. The pure whiteness of this composite material gives outstanding aesthetic properties to the final ceramic.The ATZ ColorYZe-Arctic White is suitable either for structural ceramics looking for mechanical performance, or aesthetic ceramics searching for an intense white color.
- Improved hardness resistance compared to standard Y-TZP
- Ceramic with high mechanical performance (Toughness of 6 MPa.M1/2 , Bending strength of 1100MPa).
- Pure white color for aesthetic ceramics
ColorYZe-Arctic White is proposed either as a dry powder (ColorYZe-Arctic White), as ready-to-press granules (ColorYZe-Arctic White -G)..
