## Abstract α‐CaSiO~3~ ceramics of nominal composition CaO 46.0, SiO~2~ 54.0, and Na~2~O 0.4 mass% were soaked in simulated body fluid (SBF). The soaking systems were maintained under both static and flowing conditions to study their effect on the formation of hydroxyapatite (HAp). Two different fl

✦ Synopsis
In the present work a method to determine the pH at bioceramics-simulated body fluid interfaces has been developed. The results obtained with several bioactive silica-based bioceramic materials are used to propose a general mechanism for hydroxyapatite formation.

It has been shown that the prerequisite for glasses and glass-ceramics to bond to living bone is the formation of a layer of biologically active bonelike apatite on their surfaces. The hydrated silica formed on the surfaces of glasses and glass-ceramics plays an important role in nucleating the apat
