N2 - This report describes the direct melt processing of inorganic tin fluorophosphate (TFP) glass fibers with average diameters ranging from 2 to 4 lm via centrifugal Forcespinning. This was accomplished by using a TFP glass with low glass transition temperature (Tg) and the melt processing capability of Forcespinning. The thermal behavior of TFP glass fibers was investigated by differential scanning calorimetry and thermogravimetric analysis, while the compositional evolution of the fibers was studied using energy-dispersive spectrometry and Fouriertransform infrared spectroscopy. These fibers exhibited excellent thermal stability after thermal post-treatment at 300 ℃. The Tg of the thermally treated fibers increased by 100 ℃ compared to the bulk material. The fibers were found to undergo dehydration and loss of fluorine during thermal treatment, resulting in a rigid and crosslinked glass network with enhanced thermal stability and increased Tg. The enhanced thermal stability demonstrated the potential of TFP fibers for high temperature catalysis and chemical filtration applications.
