<b>Synthesis and Characterization of Magnesium Borate via Sol Gel Method and Electrospinning Method</b> The sol gel and electrospinning techniques were used to prepare the magnesium borate polyvinyl alcohol composite. The fibers of magnesium borate about 150 nm diameters, were synthesized from the inorganic organic composite fibers by high temperature calcination process. The synthesized magnesium borate nanofibers were structurally investigated by thermogravimetric differential thermal analysis TG DTA , Fourier transform infrared spectroscopy FT IR , X ray diffractometry XRD and Scanning electron microscopy SEM , respectively. Due to the Mg modification of the B2O3 network, incomplete crystallization of the samples was observed when heat treated at 800 °C. But, completely crystalline fibers were obtained after calcined at 1200 ° C.
