摘要：

Some ternary borate glasses of varying compositions were prepared and corrosion behaviors of such ternary borate glasses after immersion in aqueous dilute phosphate solution were studied using different immersion times. Fourier transform infrared (FTIR) absorption spectral measurements were done before and after immersion in the mentioned solution for extended times up to 3 days to justify the appearance of the characteristic FT infrared bands due to calcium phosphate (hydroxyapatite (HA)) which is considered as the potential indication of bone bonding ability. Experimental IR data confirm the beginning of the appearance of FTIR bands at about 580 and 650 cm(-1) after 1 day and the complete resolution with its characteristic split form after 3 days and more. The corrosion behavior of the studied borate glasses is explained in relation to a suggested hydrolysis and direct dissolution mechanism. The ease of dissolution of all the borate glasses constituents explains the rapid conversion and formation of hydroxyapatite within the borate glass matrix as indicated and confirmed by X-ray diffraction.
