Abstract
The study characterized Ogun phosphate rocks to determine its usefulness for bioactive glass production in bone tissue engineering. The need for materials suitable for implant with outstanding biocompatibility, efficient mechanical properties, high porosity, excellent wear and corrosion resistance, without eliciting negative host reaction has been a major concern. Sedimentary phosphate rock occurs as vesicular and nodular form in Ebiti village of Dahomey Basin of Ogun State Nigeria. The phosphate rocks were collected, sorted, washed, oven-dried and characterized using X-ray fluorescence, X-ray diffraction, scanning electron microscope equipped with energy dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy. The analyses revealed that the major oxides in Ebiti phosphate rock are calcium oxide (CaO) of 56.58 %, phosphate pentoxide (P₂O₅) of 24.15%, hydroxyapatite (Ca₉(PO₄)₆.Ca(OH)₂) of 79.4% and quartz (SiO2) of 7.8%, with no significant heavy metals and radioactive elements. The study concluded that Ebiti phosphate rocks in Ogun State Nigeria are suitable for bioactive glass production for bone tissue engineering applications.
