                        5 based glasses are widely used as biomaterials due to their various chemical compositions, excellent bioactivity, adjustable biodegradation and suitable mechanical properties. The structures of Na
                        2O-TiO
                        2-CaO-P
                        2O
                        5 system glasses were investigated by FTIR and FT-Raman spectroscopies. The calcium phosphate glasses have chain-like structures based on Ti-O-P linkages containing [P 
                        2O
                        7]

                        4]
                        3- groups. Some amount of TiO
                        2 enters into the glass network, in which [TiO
                        4] tetrahedra connect with [PO
                        4] tetrahedra through the P-O-Ti bonds, the remaining TiO
                        2 exists into interspaces of [PO
                        4] tetrahedra. CaO connects the two linkages in the form of Ca-O-P bonds.
