Yield Stress of Concentrated Zirconia Suspensions
In this work this technique is applied to suspensions of zirconia particles both synthesized with spherical geometry and commercial. The σ(shear stress)−γ(shear rate) curves show that the suspensions are nonideal plastic thus exhibiting a finite yield stress σ 0 and a shear-thinning flow.

ZIRCONIA PROPERTIES AND APPLICATION — A REVIEW
· zirconia were proved to be higher than those of all other ceramics for dental use and similar to those of stainless steel. Fracture toughness Zirconia is between 6 and 10 MPa m1/2 which is almost twice as high all that of alu-minum oxide ceramics. This is due to transformational toughening which gives zirconia its unique mechanical properties.
