Abstract Scope Limitations associated with bone grafts have prompted the need for bone graft substitutes, hence this work attempted to develop hydroxyapatite (HA) bone graft substitute for the treatment of bone injury. The HA was synthesized from limestone using aqueous precipitation method. Microstructural analysis was carried out using Scanning Electron Microscopy (SEM) and chemical analysis was carried out using Energy Dispersive Spectroscopy (EDS), Atomic Absorption Spectrophotometer (AAS), Fourier’s Transform Infrared Spectroscopy (FTIR) and X-ray Diffraction (XRD) techniques. Mechanical characterization was carried out using Vickers micro hardness tester and Instron universal tester. SEM findings revealed that the HA is porous while the chemical analysis affirmed that the sintered material is composed of calcium and phosphorus with an optimum hardness value of 742 HV at 9000C and compressive, tensile, hardness, fracture toughness and modulus of elasticity comparable with standard HA. Consequently, it will be a suitable bone graft substitute for dental and orthopaedic applications.
