mechanical properties of stabilized zirconia
Basic properties and types of zirconia An overview
Zirconia has mechanical properties similar to those of stainless steel. Its resistance to traction can be as high as MPa and its compression resistance is about 2000 MPa 4 . Cyclical load stresses are also tolerated well by this material.

Mechanical and thermal properties of porous yttria
ABSTRACT. This paper reports on analyses of the compressive Young s modulus (E p) compressive strength (σ p) and thermal conductivity (κ) of sintered porous yttria-stabilized zirconia compacts (YSZ).The E p and σ p values are affected by the number of grains and the grain boundary area in sintered YSZ ceramics. The measured porosity dependence of the E p and σ p values was compared
