Multi component lithium disilicate based glasses containing P2O5 have been synthesized by conventional melt quenching technique. The replacement of (Li2O + SiO2) and its nucleating effect has discussed. Structural features were evaluated differential thermal analysis (DTA), Fourier transform infrared (FTIR) Raman spectroscopy. glass samples converted into ceramics following three stage heat tre...
