Description:
The Y 3 Fe 5 O 12 -based ferrite, i.e., Y 3-X Gd X Fe 5 O 12 system was synthesized using a reverse coprecipitation method for application of new thermal coagulation therapy using an AC magnetic field for the treatment of cancerous tissues. The mixed phase of the Y 3 Fe 5 O 12 -type orthorhombic and cubic materials without any impurities were obtained for this systems calcined at low temperature in XRD results. However the orthorhombic phase almost disappeared by the calcination at 1150 °C or higher temperature for all the X samples. The calcination temperature strongly influenced the heat generation ability. The maximum heat generation ability (ΔT = 40-63°C, 370kHz, 1.77kA/m) was obtained for the powder materials sintered at 1100 °C for the Y 3-X Gd X Fe 5 O 12 system. The particle growth with the formation of the cubic single phase strongly influenced...
