A compositionally complex (Ca, Sr, Ba)ZrO3 (CC-CSBZ) fibrous membrane with perovskite structure was successfully prepared via a simple electrospinning method. The formation, phase transformation and microstructure evolution of CC-CSBZ fibers were fully discussed. X-ray diffraction, Raman spectra and transmission electron microscopy analyses confirmed the formation and phase transformation of CC-CSBZ solid solution at high temperatures. Scanning electron microscopy results indicated that a slower grain growth rate and more stable high-temperature microstructure were achieved for CC-CSBZ fibers compared with previous BaZrO3 and CaZrO3 fibers. CC-CSBZ fibrous membrane also exhibited excellent flexibility at 1000 degrees C and high thermal stability at 1200 degrees C. Furthermore, an average near infrared reflectivity of 98% at least at room temperature was obtained for CC-CSBZ fibrous membrane heat-treated from 800 to 1400 degrees C. For the slow grain growth rate, excellent high-temperature stability and near infrared reflectance, CC-CSBZ fibrous membrane would be a promising and novel ceramic fiber product for high temperature applications.
