SEM images of (a) ceramic ZrO2-Y2O3 nanofibers (molar ratio 96/4) calcinated at 1200 °C; (b) ceramic ZrO2-SiO2 (molar ratio 80/20) nanofibers calcinated at 1200 °C; (c) ceramic ZS nanofibers calcinated at 1400 °C; (d) ceramic ZrO2-Y2O3-SiO2 nanofibers (molar ratio 76.8/3.2/20) calcinated at 1200 °C. (All fibers are electrospun from the sol containing 1.5 M ZrO2 and 1.5% PEO. All images have magnification of 50,000).
