Table of Weibull Moduli for Common Materials
Material Weibull Modulus
Silicon Nitride 20[1]
Silicon Carbide 18[1]
Aluminum Nitride 10[1]
Aluminum Oxide (98%) 10[1]
Aluminum Oxide (99%) 10[1]
Zirconia Toughened Alumina (ZTA) 13[1]
Boron Carbide 12[1]
Titanium Diboride 11[1]
Zirconia 15[1]

It is important to note that the Weibull Modulus is a fitting parameter, and therefore the reported value may vary from source to source.
