The alumina fiber was obtained by extruding the TEA complexed polymeric sol, synthesized by the alkoxide sol-gel method, through nozzle. The purpose of this study was to investigate the properties of fiber spun by TEA complexed sol. The analysis of sol indicated that TEA was bonded at alkoxide precursor and the optimum molar ratio for spinning was 0.5 mole of TEA, 3 mole of H2O. The cross section of the fiber from circular nozzle was not circular but oval, which indicated that the shape of nozzle did not affect the shape of fiber. The diameter of the fiber was about 100 ${mu}{ extrm}{m}$ in the state of dried gel fiber, 60${mu}{ extrm}{m}$ in calcined fiber, and the tensile strength of the fiber calcined at 90$0^{circ}C$ was 2.1$ imes$108 Pa.
