characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermo-gravimetric/differential scanning calorimetry and scanning electron microscopy. The results show that spinnability of gel largely depends on molecular structure of metal-carboxylate complex that is a linear-type structure formed in the gel. As a result, the gels exhibit a good spinnability. Metal Ni, Co and Fe fine......
decomposition process and morphologies of the gel precursors and fibers derived from thermal reduction of the gel precursors were characterized by FTIR, XRD, TG/DSC and SEM. The gel spinnability largely depends on the molecular structure of metal- carboxylates formed during the gel formation. The gel consisting of linear-type structural molecules shows good spinnability. Key words: organic gel......

with good quality.The results show that spinning temperature has distinct influence on forming quality of spun workpieces.The range of spinning temperature determines the spinnability of titanium alloy......
> The effects of plastic deformation inhomogeneity on spinnability and forming quality of Ti 15 3 during the process of cold power spinning were studied. The results show that the inhomogeneity of plastic......
of content of malic acid and polyvinylpyrrolidone (PVP) on sol spinnability were explored. The gel fibers with above 80 cm in length were obtained by mixing aluminum nitrate, malic acid and PVP on mass...; (3) The macroscopic properties of the precursor sols prepared with different amounts of malic acid or spinning additive are listed in Table 1. The spinnability of sol was affected......
: A new polymer named polyferrocarbosilane(PFCS) was prepared from polydimethylsilane and ferrocene. The spinnability of this polymer can be tailored by controlling the content of ferrocene...), is synthesized by chemical method, which exhibits a good spinnability, and is converted to magnetic Si-Fe-C-O continuous fibers successfully by high temperature pyrolysis in inert atmosphere......
