Preparation and synthesis of hydroxyapatite bio-ceramic from bovine bone by thermal heat treatment

Calcium phosphate, particularly hydroxyapatite (HAp) is an important material in biomedical engineering applications. The development of HAp is continued rising due to the similarity and biomimetic requirements to the hard tissue of human body such as bone and dental. The purpose of our work was to produce and describe HAp bioceramic powder from environmental and cheap source (Bovine bone) by thermal process at various calcination temperatures. The analysis of Fourier transform infrared spectroscopy (FTIR) verified the formation of HAp because of the existence peaks related to phosphate and hydroxyl groups. The analysis of Raman confirmed findings of the FTIR the formation of HAp due to the appearance of peaks at 960 and 920 cm(-1) related to a phosphate group. A result of Energy-dispersive X-ray spectrometry (EDS) also referred to Ca/P atomic ratio at 1000 degrees C was 1.6 that has been near stoichiometric hydroxyapatite (1.67) in human body.
