摘要: Abstract Uniaxially aligned mullite ceramic fibers were prepared by electrospinning a polyacrylonitrile/mullite sol mixture with rotating drum simultaneously acting as collection device followed sintering. A novel precursor was synthesized using N,N-dimethylformamide solvent. The mean diameter of the particles 15.6 ± 5.7 nm. crystal development and micromorphological evolution both as-electrospun composite sintered investigated scanning electron microscopy, X-ray diffractometry, thermogravimetry–differential calorimetry, Fourier transform infrared spectroscopy. sintering temperature played an important role in controlling surface morphology, diameters, structure fibers. Upon at 1000 1300 °C, metastable tetragonal phase stable orthorhombic obtained.
