Abstract :

About 25% of iron oxides in the sintering process are wasted. In this paper sintering waste (SW) were used as raw materials for hard and soft magnetic glass ceramics (H-, SMGC). About 71% by wt. of SW was used for preparing SMGC, while ~46% was used for HMGC preparation, Differential thermal analysis revealed one broad exothermic peak at 830├?┬?C for HMGC and at 803├?┬?C for SMGC. X-ray diffraction shows crystallization of hematite and Zn-ferrite phases in SW and Zn-ferrite and Ba hexaferrite in SMGC and HMGC respectively. Transmission electron microscope revealed crystallization of nanosize particles > 20 nm for SMGC and < 15nm for HMGC. Vibrating scanning magnetometer revealed increasing in saturation magnetization from ~26 emu/g for SW to ~44 emu/g for SMGC and decreased to ~12 emu/g for HMGC.
