Abstract

Preparation of SiO₂-TiO₂ fibers containing various TiO₂ contents by a new method was investigated. In order to obtain polytitanosiloxanes (PTS), a precursor, partially hydrolyzed tetraethoxysilane (TEOS) was brought into reaction with bis (2, 4-pentanedionato) titanium diisopropoxide (PTP) in methanol in various molar ratios of TEOS/PTP from 1 to 15. Concentration of the resultant methanol solutions of PTS gave sols with spinnability, from which SiO₂-TiO₂ ceramic fibers containing 5-50 TiO₂ mol% were prepared.
