Tetragonalzirconia

2023年2月17日 — Tetragonal zirconia polycrystal (TZP) is commonly stabilized with 3% to 5% Yttria and has the finest grain size.

ZrO₂ crystallizes in the tetragonal P4₂/nmc space group. Zr⁴⁺ is bonded in a distorted body-centered cubic geometry to eight equivalent O²⁻ atoms.

These grades exhibit the highest toughness at room temperature, because they are nearly 100% tetragonal, but this degrades severely between 200 and 500 °C as ...

Cubic Zirconia: This single crystal optically clear form of ZrO2 has a relatively low fracture toughness and strength, but very high thermal shock resistance.
