Influence of TiO2 and thermal processing on morphological, structural and magnetic properties of Fe2O3/MnO2 modified glass-ceramics

2019 
Abstract The present report is an investigation of morphological, structural and magnetic properties of multicomponent glass-ceramics with respect to content of nucleating agent (TiO 2 ) as well as thermal processing parameters. Structural features of these glass-ceramics were explored by their crystalline phase analysis and morphological studies after sintering at various temperatures (850–1000 °C) for 2 h (h). The samples exhibited near superparamagnetic nature which would be helpful for heat generation purposes (such as in hyperthermia treatment of cancer). Magnetic properties of the glass-ceramics are dependent on the crystallized phases grown upon sintering. Concentration dependent role of TiO 2 is discussed based upon the obtained results.
