In recent years, the development of composite biomaterials has been the subject of very intensive research. The elaboration of technology for manufacturing new biomaterials will allow their practical implementation and adaptation to changing market needs. One of the key components in the developed composite materials will be natural origin hydroxyapatite (HAp) and tricalcium phosphate (TCP) obtained from bone products. In this study, preparation and detailed characterization of bone-derived calcium phosphates as a component of biomaterial composites is proposed. This novel method of obtaining hydroxyapatite for biomedical applications allows the obtainment of a material with expected parameters. In this study, pork bones from meat cutting were subjected to a three-stage treatment: acid hydrolysis, initial calcination and proper calcination. In order to investigate the effect of lactic acid on the properties of the obtained materials, the preparation of a series of hydrolysis reactions with an increasing content of the hydrolysis reagent was assumed. Moreover, the third step of material preparation—proper calcination—was carried out at various temperature and time parameters. Subsequently, several experimental techniques were employed to investigate the expedient physicochemical properties of all calcium phosphate powders.
