The results showed that heat treatment had no obvious effect on main linkage way of the system. Between 500℃and 900℃, the crystal phase CaF_2 was precipitated firstly, with the rising of temperature and the prolonging of time, crystal phases such as Al_2SiO_5、Ca_2SiO_4 and Ca_3(PO_4)_2 were precipitated sequentially and the powder was changed from dispersive spheroidic to irregular strip that linked each other, and congregated to irregular mass, gradually.
