摘　　要：Elastic zirconium-based ceramic fiber products have gain particular interest due to their exceptional hightemperature resistant performance.Nonetheless,commercial high-performance Zr-based fibers are still difficult to acquire which hinders its widely application in thermal insulation scenes.Herein,large-scale fabrication of various Zr-based(ZrO_(2),ZrSiO_(4))ceramic fibers were achieved through solution blow spinning technology,which was endowed with merits such as cost-effectiveness,high production efficiency,reduced energy consumption,and exceptional product quality.Through high-temperature sintering to 1000°C,blow spun organic fibers can be converted into Zr-based ceramic fibers with diameters ranging from 0.5 to 2μm.Optimizing the crystalline structure of these fibers through high-temperature pyrolysis process enhanced their thermal resistance.Additionally,through introducing polysiloxane as the Si source,ZrSiO_(4)fibers can be synthesized with markedly improved mechanical properties and high-temperature resistance.These blow-spun Zr-based fiber sponges exhibit advantageous internal pore structures,high-temperature elasticity and thermal insulation performance.
