Fast fracture strength data on slip‐cast reaction‐bonded Si 3 N 4 determined by uniaxial MOR, biaxial ball‐on‐ring tests, and speed of rotational failure measurements were correlated using Weibull statistics and finite‐element techniques. The agreement between predicted and observed values demonstrated the applicability of the Weibull equation.
