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.
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.
