Alumina fibres were obrained by impregnation of the cellulose biotemplate with precursor solutions in which the hydrolysis ratio [OH-]/[Al3+] is varied and in which different aluminium oligo- and polycations content. The biotemplates and alumina fibres were studied by X-ray, TG/DSC, electrophoretic light scattering, SEM, and N2 adsorption/desorption. It was shown that the infiltration with the precursor did not affect the cellulose structure. The possibility to vary the surface area, pore size and pore volume of the ceramic fibres by controlled hydrolysis of aluminum was demonstrated.
