Notes:
In the present work the behaviour of HAp extracted from pig bones at elevatedtemperatures up to 1000oC in O2 and CO2 atmospheres has been studied. It has been found that CO2atmosphere arrests HAp decomposition. Chemical analysis and infrared spectroscopy reveal that nofree CaO appears and no decrease of CO3-2 concentration groups occurs in the material calcined inCO2 atmosphere. In the O2 atmosphere at elevated temperatures CaO and CO2 are emitted from thesamples, although the remaining material retains the HAp structure as indicated by the X-raydiffraction
