High iron containing ash from an Egyptian coal power station was mixed with borosilicate glass powder of Pyrex composition in order to fabricate glass ceramic materials by the sintering technique. The concentration of glass ranged from 0-60wt%. Samples containing ash and glass in a 50/50 proportion and sintered at 1500 deg C for 5 hours showed the best results in terms of densification and microstructure development. Moreover, these samples exhibited magnetic properties which were related to the presence of a ferrite type phase. Magnetisation curves typical of soft magnetic materials were measured by the vibrating sample magnetometer technique. The present result show a convenient way to treat iron containing ash, transforming it into useful glass ceramic products via a simple and cost effective powder technology and sintering route.
