Abstract
.alpha.-Alumina fibers are produced by a sol-gel process using aluminum nitrate as a starting material. A reaction mixture including aluminum nitrate, water and aluminum particles is refluxed until the aluminum particles are completely dissolved to obtain an aluminum hydroxide sol. The aluminum hydroxide sol is then aged to increase the viscosity thereof, spun, dried and sintered to obtain .alpha.-alumina crystalline fibers.
