Structural and magnetic properties of SiO 2-CaO-Na 2O-P 2O 5 containing BaO-Fe 2O 3 glass-ceramics

The incorporation method was employed to produce bioactive glass-ceramics from the BaFe 12O 19-SiO 2-CaO-Na 2O-P 2O 5 glass system. The ferrimagnetic BaFe 12O 19 was first prepared using a simple mixed oxide method, where the oxide precursors of 45S5 bioglass were initially mixed and then melted to...
