3 mol% Yttria-Stabilized Zirconia

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. Pigmented zirconia for decorative fine ceramic applications is also available. Please refer to ColorYZe page for more information.

All ZirPro powders are manufactured using a state-of-the-art chemical process to ensure excellent performance and consistent high quality.

Sixty microns RTP granule

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.
