The passage around this formula
with m the Weibull modulus and a scale parameter. A larger m means tighter scatter. A review of Weibull analysis across ceramics reports moduli of roughly 10 or below for many advanced ceramics such as alumina, hydroxyapatite and silicon carbide, below about 7 for the glass-ceramics and zirconias surveyed, and above 40 for one magnesium-based glass, while emphasising that reliable modulus estimates need substantial sample sizes [ 11 ] .
