| CaO-P 2O
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- groups and [PO
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.
