The superior physical properties of yttrium-stabilized zirconia powder include:
High fracture toughness: Up to 14 MPa·m¹/², exhibiting excellent resistance to crack propagation, suitable for structural components under high stress environments.
High fracture toughness: Up to 14 MPa·m¹/², exhibiting excellent resistance to crack propagation, suitable for structural components under high stress environments.
High strength and high hardness: After sintering, the flexural strength reaches 1000 MPa, and the Vickers hardness is HV1300, making it suitable for use as grinding media and wear-resistant parts.
Ultra-fine nanostructure: Primary particle diameter is only 200–400 angstroms (20–40 nm), ensuring material uniformity and dense sintering.
Yttrium-stabilized zirconia powder features a stable crystal structure.
By adding 6–8 wt% Y₂O₃, the tetragonal or cubic phase of zirconia is stabilized, preventing cracking caused by high-temperature phase transitions and significantly improving material reliability.
The doping ratio can be customized according to the application, such as 3 mol% Y₂O₃ for dental ceramics (3Y-TZP) and 8 mol% Y₂O₃ for fuel cell electrolytes (cubic phase YSZ).
Yttrium-stabilized zirconia powder offers versatile application adaptability.
Biomedical field: Used in dental crowns, bridges, and implant abutments, exhibiting good biocompatibility, low surface bacterial adhesion, and a lifespan exceeding 15 years.
Energy field: As an electrolyte for solid oxide fuel cells (SOFCs), it exhibits an ionic conductivity > 0.1 S/cm at 800°C and an energy conversion efficiency of up to 70%.
Industrial Grinding: Yttrium-stabilized zirconia spheres are produced with a wear rate ≤ 4 ppm/hr, enabling fine grinding of powder particles to 0.45–0.55 μm, widely used in electronic ceramics and lithium battery material processing.
High-Temperature Components: With a long-term operating temperature up to 2400℃ and a refractoriness of 2500℃, it is suitable for extreme environments such as vacuum induction melting crucibles and ultra-high temperature furnace linings.
Excellent Processing Properties of Yttrium-Stabilized Zirconia Powder: Utilizing a spray-drying granulation process, the standard particle diameter is approximately 50 micrometers, exhibiting good flowability (Hall flow rate >30 seconds/50 grams), suitable for dry pressing and isostatic pressing.
Digital machining using CAD/CAM technology enables precise fabrication of complex shapes, particularly suitable for dental restorations.
