การเตรียมและการวิเคราะห์แก้วและแก้วเซรามิกชีวภาพจากระบบแคลเซียมโซเดียมฟอสเฟต

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.
