PURPOSE:To provide an inorganic filament composed of amorphous substance consisting of Si, C, Ti, etc., Cr, etc., and O, having specific element ratios and high mechanical strength, exhibiting excellent wettability to various matrices and having heat-resistance. CONSTITUTION:Xylene is added to a mixture of polycarbosilane, titanium tetrabutoxide and dioxobis (acetylacetonato) molybdenum and the components are made to react under thermal refluxing at 120 deg.C for 0.5hr in nitrogen gas stream. After removing xylene, the reactional product is polymerized at 350 deg.C for 1hr and the obtained organometallic polymer is spun by melt-spinning to obtain a fiber. The fiber is infusibilized by heating at 190 deg.C for 4hr and baked by raising the temperature to 1300 deg.C in nitrogen gas stream without applying tension to obtain the objective inorganic filament composed of an amorphous substance consisting of Si, C, M<1> (M<1> is Ti and/or Zr), M<2> (M<2> is Cr and/or Mo) and O and having element ratios of 40-60wt.% of Si, 20-40wt.% of C, 0.5-10wt.% of M<1>, 0.1-5wt.% of M<2> and 0.01-30wt.% of O. |
