METHOD FOR PRODUCING METAL OXIDE FIBERS, AND METAL OXIDE FIBERS
In one aspect of the present invention, provided is a method of producing a metal oxide fiber, including a spinning step of spinning a composition containing polymetalloxane and an organic solvent to obtain a thread-like product; and a firing step of firing the thread-like product obtained in the spinning step at a temperature of 200°C or higher and 2,000°C or lower to obtain a metal oxide fiber. The polymetalloxane has a repeating structure composed of a metal atom selected from the group consisting of Al, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Y, Zr, Nb, Mo, Pd, Ag, In, Sn, Sb, Hf, Ta, W and Bi, and an oxygen atom. The weight average molecular weight of the polymetalloxane is 20,000 or more and 2,000,000 or less.
