| Abstract: | Metaphosphate and pyrophosphosphate groups coexisted in 50 CaO*(50-x)P2O5*xAl２O３(x=0～7.5)glasses according to FT-IR spectrum.But their relative amounts changed with the composition.The higher the O/P molar ratio,the less the metaphosphate,while the later was on the other way round.This may led to the crystallization of different crystal phases.Al3+located in the void of the netwok,increasing the viscosity of the glass melt,and retarde the phase separation. |
