The fracture strength of an α‐ and β‐SiAION was measured by biaxial and four‐point bending. By utilizing Weibull statistics a close prediction could be made of the four‐point values from the biaxial values. At a fracture strength of 460 MPa, fracture was initiated by linking of surface and subsurface flaws.
