In the present study, magnetic glass ceramics in the system Fe2O3 ∙ TiO2 ∙ P2O5 ∙ SiO2 ∙ MO (M=Mg, Ca, Mn, Cu, Zn or Ce) are prepared. The effect of adding different cations on the thermal behavior, developed phases, microstructure and magnetic properties is studied using differental thermal analysis (DTA), X-ray diffraction analysis (XRD), transmission(More)
This work pointed out the effect of adding P2O5 and/or MnO2 on the crystallization behavior of magnetic glass ceramic in the system Fe2O3·ZnO·CaO·SiO2·B2O3. The differential thermal analysis of the quenched samples revealed decrease in the thermal effects by adding P2O5 and/or MnO2 to the base sample. The X-ray diffraction patterns show the development of(More)
This work pointed out the anti-cancer effect of ferrimagnetic glass ceramic nanocomposites (CaO-ZnO-Fe2O3-SiO2), which contain high amount of magnetite (∼60%), crystallite size <100nm, and different nucleating agents on bone cancer Saos-2 cells. The cell viability was inhibited by FH and FW to <50% and <25%, respectively, with/without magnetism, and both(More)
The present study aimed at studying the acceleration of the bioactive layer on the surface of ferrimagnetic glass ceramic with a basic composition 40Fe2O3-15P2O5-20SiO2-5TiO2 through the addition of 20% of different types of metal oxides like MgO or CaO or MnO or CuO or ZnO or CeO2. SEM, EDAX, and ICP were applied to present the results of the study. SEM(More)
