Abstract
The influence of fine-disperse iron oxide particles on the structure of alumina fibers prepared via the template synthesis has been studied. The template (fibers of bleached cotton cellulose) has been impregnated with mixed aqueous dispersions of aluminum and iron(III) hydroxides prepared via the sol–gel route. Thermal treatment of the precursor has afforded alumina ceramic fibers with average diameter of 3–10 µm containing uniformly distributed iron(III) oxide nanoparticles at the surface. Increase of the iron(III) oxide nanoparticles concentration has deteriorated the texture properties of the product.
