The interaction of sol-gel derived glass/organic polymer composite gel monoliths, containing a calcium salt, with an ambient solution of simulated body fluid was investigated. These gels were aged, wetted, placed in simulated body fluid, and then observed with a scanning electron microscope. The chemical compositions of the sample and the apatite were determined by energy dispersive X-ray analysis. A calcium phosphate apatite layer was clearly observed after 7 days, as was an intermediate layer which included not only calcium and phosphate in its composition but also silicon. Calcium and phosphate were also observed to be present in the outer layer of the sample, presumably having precipitated on the external surfaces of the pores in the SiO2 network.
