Abstract
Novel magnetic A–W glass ceramic (M GC) in the system MgO–CaO–SiO 2–P 2O 5–CaF 2–MnO–ZnO–Fe 2O 3 was synthesized by doping Mn–Zn ferrite to apatite–wollastonite glass ceramic. The phase composition was investigated by XRD. The magnetic property was measured by VSM. The in vitro bioactivity was tested by immersion in simulated body fluid. The result shows apatite, wollastonite, fluorapatite and Zn 0.75Mn 0.75Fe 1.5O 4 are the main phases of M GC. Under a magnetic field of 10,000 Oe, the saturation magnetization and coercive force of the material are 6 emu g − and 180 Oe, respectively. After soaking in SBF for 14 days, the surface of M GC is coated by a hydroxycarbonate apatite layer.
