By means of IR and Raman spectra, TEM, DTA, XRD and EDAX techniques, the influence of P_2O_5 on structure, phase separation and crystallization of CaO-MgO-Al_2O_2-SiO_2-P_2O_5-F glasses was investigated and the relationship among them is described in detail. The results show that glasses in the system bays tow-phase separation structure, the droplet phase is rich in P~(5+), Ca~(2+), Mg~(2+) and the matrix phase is rich in Si~(4+), Al~(3+). Adding different amount of P_2O_5, the extent of glass phase separation...

The results show that glasses in the system bays tow-phase separation structure, the droplet phase is rich in P~(5+), Ca~(2+), Mg~(2+) and the matrix phase is rich in Si~(4+), Al~(3+). Adding different amount of P_2O_5, the extent of glass phase separation is different, and it has marked influence on glass polymerization degree and crystallization process.

There is a critical point in all glass phase separation boundaries.The phasetransition at this point belongs to continuous phase transition.By the discussionin this paper,it has been known that the phase separation in binary glass systemscan be described by the modern continuous phase transition theory.The equationsfor the immiscible curves at the two sides of the neighborhood of the critical pointare:(x′-x_c)/x_c=A[(T_c-T)/T_c]~(1/3),(x′-x_c)/x_c=A′[(T_c-T)/T_c](1/3).Here A andA′are universal constants of immiscible curves.In this paper,the fitting results ofA and A′from Li_2O-SiO_2,Na_2O-SiO_2,BaO-SiO_2 system′s experimental data ofphase separation are A=-1.8305:A′=2.3551.The corresponding calculated curvesfit the experimental data very well.Further research will be done for getting moreaccurate universal A and A′.
