Abstract
A new process for producing an inorganic fiber of superior tensile strength and modulus of elasticity, which comprises spinning a spinning solution in organic solvent of polymetaloxane of good spinnability to form a precursor fiber, calcining said precursor fiber, and wherein said solution contains polymetaloxane comprising 0.1-95 mole % of a structural unit represented by the following general formula [A] and 99.9-5 mole % of the following formula [B]: ##STR1## (wherein, M represents a trivalent or tetravalent metal atom, X.sub.1 represents an organic group which is the same as or different from ##STR2## hydrogen, nitro or halogen, X.sub.2 and X.sub.3 represent an organic group other than ##STR3## Y represents an organic group, nitro or halogen, m represents an integer from 1 to 3.).
