The aim of this work was to study the magnetic properties of magnetic glassceramics
with composition system CaO-Na2O-P2O5-BaO-Fe2O3. The magnetic glass–
ceramics were prepared by conventional melting at 1300oC for 2 h of the coprecipitation
derived starting products and heat treated at different temperatures. The structure and
microstructure of the samples were characterized by X-ray diffraction, energy dispersive
X-ray analysis (EDXA) and scanning electron microscopy. The magnetic measurement
showed that the samples which contained barium ferrite exhibited magnetic behavior
which is similar to soft magnetic materials. Finally, the samples were soaked in
simulated body fluid (SBF) for 14 days. The apatite was found to form on the surface
layer of glass-ceramics and it increases with the barium ferrite content was increased.
