Comparing Properties of Bovine Bone Derived Hydroxyapatite and Synthetic Hydroxyapatite

Abstract

Some waste materials from natural sources are interesting resources for extraction to a more valuable compound. Specific techniques for the extraction of these waste materials are required. Hydroxyapatite (HAp) is one of the most important biomaterials that can be extracted from natural Bovine Bone waste. Natural Hydroxyapatite has been extracted from bovine bone by heating it at different temperatures, namely 850°C and 900°C. The properties of this natural hydroxyapatite have been compared with synthetic hydroxyapatite obtained from a commercial product. The influence of the HAp extraction method on several critical properties such as Ca/P ratio, crystal structure, crystallinity, crystallite sizes, microstrain, and morphology have been discussed. The hydroxyapatite obtained from the bovine bone was around 51% wt. The volume of the unit cell, crystallinity, crystallite size, ratio Ca/P, and morphology were affected by the extraction process. The conclusion is that HAp obtained from bovine bone is comparable to commercial products.
