Formation Mechanism of Multilayered Structure on Surface of Bioactive Borosilicate Glass
A conversion process of a bioactive borosilicate glass to a multilayered structure in aqueous phosphate solution was described. Microstructure, morphology and composition of the reaction product were studied using XRD, SEM and EDS analysis. It was shown that a multilayered structure, consisting of alternating hydroxyapatite (HA) and amorphous SiO2 layers, was formed on the surface of the borosilicate glass. The formation mechanism of the multilayered microstructure was also suggested. Compared with previous work, it was indicated that conversion kinetics and microstructure development of conversion products mainly depended on the composition of the bioactive glass and the concentration of phosphate solution.
