The TiO2 coating films were applied to the artificial graphite plates through the sol-gel route using the dip coating technique. The TiO2 sol for the dip-coating was prepared by hydrolyzing titanium tetra-iso-propoxide in ethanol. The addition of HCl or diethanolamine was effective for stabilizing sols.
The TiO2 films thus obtained was heated to 1100°C in the.flow of NH3 gas to form titanium nitride which was still 'nonstoichiometric, but colored in brownish yellow. Relatively high adhesion of the film to the graphite was achieved. The nitridation process of the sol-gel derived TiO2 films was investigated.
