Title

THE EFFECTS OF HEAT TREATMENT AND ATMOSPHERE ON MAGNETIC PROPERTIES OF NANO-STRUCTURED NICKEL FERRITE GLASS-CERAMIC

Pages

  91-99

Abstract

 The effects of temperature, time and atmosphere on microstructure and MAGNETIC PROPERTIES of NiFe2O4 glass ceramic were investigated utilizing differential thermal analysis, X-ray diffraction, vibrating sample magnetometer and scanning electron microscope techniques. Various compositions were studied in the Na2O-NiO-Fe2O3-B2O3-SiO2 system to obtain amorphous phase. The sample heat-treated in graphite bed at 510o C for 1 hr showed higher magnetization than the one heattreated in the air under the same condition. XRD analysis showed the presence of NICKEL FERRITE and some non-magnetic phases such as sodium borate and silicate phases in the heat treated samples. The maximum magnetization of samples reduced by increasing the holding time from 1hr to 3 hr at 510o C. Increment of temperature to 700o C increased the amount of NiFe2O4 and maximum magnetization.
