In this study, the Weibull distribution of five (5) hydroxyapatite (HAp) samples produced from a novel mixture of naturally derived biowastes using the sol-gel method is reported. Compressive strength values were used to estimate the Weibull parameters. The structural, morphological, and mechanical properties of the as-produced HAp materials were investigated. The results revealed the typical hexagonal crystal structure of HAp materials. Data obtained from the Weibull analysis are comparable to the data in the literature and show how an increase in porosity is related to the Weibull modulus (m). The C100 sample showed the highest Weibull modulus.
