Yttria-Stabilized Zirconia (YSZ) Powder
High-purity yttria-stabilized zirconia powder — grade KG-ZRO99-20
Zirconia (ZrO₂) material overview
Zirconia is a tough engineering ceramic with high strength, wear resistance and excellent surface-finish potential. Thanks to its phase-transformation toughening mechanism, it offers fracture toughness far above typical ceramics, making it ideal for precision mechanical and wear parts. Khat Group supplies yttria-stabilized zirconia (YSZ) powder for blades, plungers, sleeves, rollers, pins and custom precision components across medical, consumer, industrial and fluid-handling systems.

Featured product — KG-ZRO99-20
The featured commercial grade is a high-purity yttria-stabilized zirconia powder in the fine-milled fraction:
| Attribute | KG-ZRO99-20 |
|---|---|
| Purity | ≥ 99.5% |
| Particle size | < 5 µm |
| Stabilizer | Yttria (~3 mol%) |
