چکیده انگلیسی
The devitrification of iron oxide containing waste generated from mixing blast furnace slag and blast furnace flue dust has shown magnetic characteristics. An investigation of the room temperature M-H hysteresis loops and saturation magnetization has been conducted in a different composition of iron-rich glass-ceramics with grain sizes ranging from â45 to 500 μm and at different heat treatment crystallization. Analysis of hysteresis loop data for sample heat treated at 900 °C for 2 h yielded values of 0.7 emu/g and 57.6 Oe for the saturation magnetization and coercitive force, respectively. Pyroxene and magnetite were identified as two major phases after heat treatment. Results of thermal expansion and density of the crystallized glass are also reported.
