Development and application of fluorine free mould fluxes have been widely studied in recent years. Some research has shown that B2O3 and TiO2 are potential substitutes for F– in mold fluxes. In this study, Structure of CaO–B2O3–SiO2–TiO2 glass system has been studied by Raman spectroscopy. The influence of basicities (CaO/SiO2) and contents of B2O3 and TiO2 on the structure of CaO–B2O3–SiO2–TiO2 glasses were examined. Experimental results indicate that TiO2 exists in the system in the form of [TiO4] as network former in range of 0–15% in mass. The degree of polymerization of this system decreases with increase of basicities. The increase of B2O3 leads to more [BO4] tetrahedral units. It is concluded that both B2O3 and TiO2 behave as network forming oxides within the studied system.
