Discontinuous ${gamma}$-LiAlO2 fibers for fiber-reinforcing MCFC matrixes have been produced by the sol-gel process using the centrifugal spinning apparatus of the Rotary type. Gel fibers could be obtained through spinning of stable LiAlO2 complex polymetric sols under the optimum spinning conditions (hollow-disc rotating velocity 9000 rpm sol feeding rate of 4ml/min flowing N2 temperature of 4$0^{circ}C$ and flowing N2 pressure of 4 bar). It was found that defect free and densified ${gamma}$-LiAlO2 fibers with the relative density of 98% and the mean diameter of 4.7${mu}{ extrm}{m}$ were prepared when the spinned fibers were heat-treated to 100$0^{circ}C$ on the specified heating schedule. in particular the mean diameter and length of fibers could be controlled by the pressure of flowing N2 and the chopping-sieving method respectively.
