In this research, the kinetics of Fluorapatite synthesis via mechanochemical route in non-isothermal conditions was studied. The reaction kinetics was investigated by means of simultaneous thermal analysis(STA) instrument. The experiments were carried out under non-isothermal condition in argon atmosphere with linear heating rates of 15, 10 and 7 ◦C/min. The Coats-Redfern approximation was used to determine the mechanism of reaction and Kinetics parameters. The results showed that the reactions are chemically controlled with mechanism of E= 16 KJmol-1.
