Porous biomorphic TiO 2 ceramics were manufactured from paper preforms by chemical vapor infiltration and reaction (CVI-R) in a three-steps process. First, the cellulose fibers of the paper were converted into carbon (C b ) by pyrolysis in an inert atmosphere. Then, C b -template was infiltrated with a precursor system consisting of TiCl 4 , CH 4 and H 2 to produce porous TiC ceramics, which were oxidized in a final step with air at temperatures in the range of 400-1200 โข C. Depending on the conversion degree, TiC/TiO 2 or TiO 2 ceramics were obtained. The kinetics of the oxidation process was studied by thermal gravimetric analysis (TGA) and activation energies of 63 and 174 kJ mol -1 were estimated for the lower (400-800 โข C) and higher (950-1200 โข C) temperature regions, respectively. The TiO 2 ceramics were characterized by Raman spectroscopy (anatase/rutile ratio), SEM/EDX (morphology, composition) and nitrogen gas adsorption (pore structure). It was shown, that the anatase/rutile ratio as well as the pore structure of the resulting TiO 2 ceramics could be controlled varying the oxidation temperature. The TiO 2 samples obtained by oxidation of TiC biomorphic porous ceramics are lightweight but nevertheless have very good mechanical performances. Their bending strength varies between 30 and 40 MPa at a porosity of 65-70%. These structures have many potential applications, e.g. light structured materials, implants because of their bio-compatibility, catalyst support or catalyst for photo catalytic applications.
