Abstract
Abstract The in vitro surface reactions of a 45S5 bioactive glass in three simulated body fluids (SBF) are analyzed using Fourier transform infrared (FTIR) spectroscopy. Five reaction stages are observed. Calcium and phosphate ions in SBF accelerate to a small extent the repolymerization of silica (Stage 3) and formation of an amorphous calcium‐phosphate (a‐CP) layer (Stage 4) on the glass surface. The a‐CaP layer is crystallized to form hydroxycarbonate apatite (HCAp) (Stage 5) more rapidly in the Ca‐and P‐containing SBF solutions (in 90 min rather than 120 min). However, Mg ions in SBF slow down formation of the a‐CaP layer and greatly retard crystallization of HCAp on the glass surface. © 1993 John Wiley & Sons, Inc.
