*3 MPa m^1/2
to
10 MPa m^1/2
[The strength of many advanced ceramics reflects the flaws present in the material and the material's intrinsic fracture toughness. Monolithic ceramics and some composite ceramics (i.e., particulate- or whisker-reinforced) will fail in a brittle fashion when stressed due to unstable propagation of cracks from preexisting flaws.]
*Pl. refer ASTMC1239-07- Standard Practice for Reporting Uniaxial Strength Data and Estimating Weibull Distribution Parameters for Advanced Ceramics.
