Electrospinning represents an interesting bottom-up approach for the development of 1D nanoscaled materials. It is a relatively simple and inexpensive to obtain continuous nanofibers for a broad range of applications. Ceramic nanofibers synthesized via e-spinnmg were only introduced in 2002 to be first used in components such as gas sensors and catalysts. In this work, magnesium borate fibers were produced by electrospinning from sol-gel precursors and annealed under different conditions. Mg_2B_2O_5 offers excellent mechanical properties combined with good heat and corrosion resistance. It is used as anti-wear material but can also work as catalyst, luminescent material, or fused cast refractory in steel-making environments. In view of a possible application of electrospun fibers on ceramic filters for metal filtration, the same treatment as for carbon-bonded alumina filter substrates was applied on the fibers.
