Abstract:

Three simulated body fluids were prepared by varying the magnesium ion content. Ceramic specimens, obtained by uniaxial pressing of wollastonite powders followed by sintering, were immersed in each simulated body fluid for different periods of time at physiological conditions of pH and temperature. In all the cases, an apatite layer was formed on the ceramic specimens. However, the morphology of the layer changed substantially. Furthermore, the crystallinity of the apatite layer decreased as the magnesium content in SBF was increased.
