Chemical coating on polycrystalline alumina fibers with smooth surface was carried out using a sol obtained by the hydrolysis of Al-sec-tributoxide (TBOA) or Si-tetraethoxide (TEOS) in ethanol. Partial deposition of TBOA-derived granules or the entire deposition of TEOS-derived thin film could be observed on the fiber. The former showed no change in appearance when heated at temperatures lower than 1400℃, and exhibited integration with the original fiber above that temperature. It was also noted that the thin film in the latter was thermally stable, keeping the smooth surface below 1400℃, while geometrical patterns evolved on the naked surface of the original fiber at the same temperature. The film thickness was estimated to be 3 nm after being dried at 90℃.
