Magnetic materials play a key-role in magnetic induction hyperthermia for the treatment of cancer. In this paper, we analyse the magneticproperties of ferrimagneticglass-ceramics with the composition in the system SiO2–Na2O–CaO–P2O5–FeO–Fe2O3, as a function of the melting temperature. These materials were obtained by melting of commercial reagents in the temperature range of 1400–1550 °C. Room-temperature magnetic measurements were performed by means of a vibrating sample magnetometer at room temperature. The power loss was determined from calorimetric measurements, using a magnetic induction furnace. The highest power loss (61 W/g) has been obtained for samples melted at 1500 °C. The heat generation of the ferrimagneticglass-ceramics prepared by two different synthesis methods (traditional melting and coprecipitation-derived) will be compared. These materials are expected to be useful in the localised treatment of cancer.

Abstract

Magnetic materials play a key-role in magnetic induction hyperthermia for the treatment of cancer. In this paper, we analyse the magneticproperties of ferrimagneticglass-ceramics with the composition in the system SiO2–Na2O–CaO–P2O5–FeO–Fe2O3, as a function of the melting temperature. These materials were obtained by melting of commercial reagents in the temperature range of 1400–1550 °C. Room-temperature magnetic measurements were performed by means of a vibrating sample magnetometer at room temperature. The power loss was determined from calorimetric measurements, using a magnetic induction furnace. The highest power loss (61 W/g) has been obtained for samples melted at 1500 °C. The heat generation of the ferrimagneticglass-ceramics prepared by two different synthesis methods (traditional melting and coprecipitation-derived) will be compared. These materials are expected to be useful in the localised treatment of cancer.
