Effects of Heat-Treatment on the Magnetic Properties of Fe₂O₃-CaO-SiO₂ Glass Ceramics

Abstract:

The Fe2O3-CaO-SiO2 glass ceramics were prepared by the method of quenching and controlled crystallisation. Differential thermal analysis, X-ray diffractometry and vibrating sample magnetometer were used to study the crystallisation and magnetic properties of Fe2O3-CaO-SiO2 glass ceramics. It was concluded that the main crystalline phases of glass ceramics during the process were Hematite, Iron Silico Oxide and Hedenbergite. The saturation magnetisation values (Ms) of glass ceramics varied between 108 emu•g-1 and 147 emu•g-1. The crystallisation of Hedenbergite lead to the high Hc value (~2000Oe).
