Possibility of fiber drawing in the course of hydrolysis has been examined to prepare refractory oxide fibers of the TiO2-SiO2 and Al2O3-SiO2 binary systems from metal alcoholates. The liquid mixtures of Ti (O-isoC3H7)4 + Si (OC2H5)4 and Al (O-isoC3H7)3 + Si (OC2H5)4 + C2H5OH were slowly hydrolyzed and became increasingly viscous when exposed to ambient atmosphere at room temperature, and so the fibers could be drawn after varying periods of time of holding. The promotion of the hydrolysis by the addition of pure water to the alcoholate mixtures could not be applied to the present method of fiber drawing, because it caused the precipitation of the hydrolyzed product. Mixture of the alcoholate solutions and water added as alcoholic solution showed no precipitation and promoted hydrolysis of the alcoholates, but it did not show spinnable state in the course of hydrolysis. Heating the drawn fibers at 500°C led to the formation of oxide glass fibers.
