Influence of ferric oxide content on performance of ferrosilicate glasses and glass fibers

The influence of ferric oxide content on the performance of melt-derived ferrimagnetic glass and glass fibers was investigated in this work. Ferrimagnetic glass fibers within ferrosilicate glass system were prepared by spinning method. The effect of ferric oxide content on the microstructure and mechanical properties of the glass fibers were examined. The X-ray diffraction analysis showed the presence of magnetite with spontaneous crystallization for all investigated samples. Transmission electron microscopy (TEM) analysis indicates that the size of magnetite is less than 30 nm in diameter. The surface microstructure, magnetic hysteresis circles, microwave absorption properties, Mössbauer spectra, thermal expansion performance, tensile properties, hardness, and elastic modulus of as-prepared samples were studied in detail.
