Low-Temperature Preparation of Biomorphic TiC/C Ceramic in Molten Salt Media
In the present work, biomorphic TiC/C ceramic with a woodlike structure was synthesized from wood template. The TiC coatings were formed on the surface of C-wood-template in a reaction medium consisting of Ti powder in a mixture of molten LiCl-KCl salts under an argon atmosphere. The structure and biomorph of the TiC/C ceramic were characterized by XRD, TG-DSC, SEM and EDX analyses. The results indicated that Ti powder had reacted with carbon in the cellular wall to form TiC coatings. The resulting biomorphic TiC/C ceramic retained well the structure of the original biomorph of the wood.
