After nucleated at 800℃ for 50 minutes and crystalized at 890℃for 70 minutes, the specimen exhibited a fine and uniformed grain size of about 20 μm under optical microscopy. Biocompatibility test for the bioglass ceramics was conducted by the cell culture and implantcd in rat shoulder.　The results showed that the specimens formed a tight chemical bond with biological texture and had a good biocompatibility.#A 3193116en-US生醫玻璃陶瓷結核結晶生物適應性貝它參鈣磷酸鹽BIOGLASS CERAMICSNUCLEATIONCRYSTALLIZATIONBIOCOMPATIBILITYβ- TRICALCIUMPHOSPHATE
