Abstract
The bioactivity of low silica glasses is contributed to the surface layer of highly hydrated silica gel formed in vivo. Phosphate precipitation in and at time gel is a complex process involving amorphous and metastable precursors to hydroxyapatite (HAP). In the gel the pH value increases towards time glass, while the molar Ca/P ratio decreases going from 1.5 close to bone to 1 at glass surface. In the present paper time formation of different calcium phosphate compounds is calculated as function of pH.
