Effect of Cr2O3 on structural and magnetic properties of SiO2–B2O3–Fe2O3–Al2O3–Na2O glass–ceramics

SiO2–B2O3–Fe2O3 magnetic glass–ceramics were prepared by conventional melt quench using a heat treatment method. The effects of Cr2O3 on the phase structure and magnetic properties of the ferrimagnetic glass–ceramics were examined by differential scanning calorimetry, photothermal measurement system, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and vibrating sample...
