3Y-TZP Zirconia Powder
CAS Numarası: 1314-23-4
3mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) powder, equivalent to Tosoh TZ-3Y. Delivers exceptional fracture toughness and flexural strength for high-performance structural and dental ceramics. ZrO₂+HfO₂ ≥94.5%, Y₂O₃ 5.15±0.2%, with tightly controlled median particle size (d50 0.3–0.6 μm) for dense, defect-free sintered bodies.
