【Abstract】 The composition ofβ-TCP is similar to that of human bone and it has a property of biodegradability,so it is used as a safe and effeetive temporary framework for repairing of bone defects.β-TCP obtained by sintering below 1000℃has a good property of biodegradability but it has a low strength and difficult to shape,whileβ-TCP obtained by sintering above 1100℃has a high strength but a poor biodegradability.Here we prepared a type of eeramic-glass composite material,whereβ-TCP was the main phase and phosphate glass was used as an adhesive.³¹p MAS NMR was used to investigate the bonding of the interface.The results indicate that that crystalline diealeium pyrophosphate（Ca₂P₂O₇）is separated at the interface of ceramic and glass,which is benefit to the strength of the material.更多还原
