Two kinds of apatite powder were prepared separately from bovine bones originated from different geographical and ecological areas with different climates, in order to characterize and compare their components, hardness and structures by burning them and heat treating the bone ashes at 850 °C in an air furnace. The black ashes were converted to white and yellow–white powders. X-ray diffraction (XRD) analysis indicate that the white powder was carbonate–hydr...
