PREPARATION OF TIN AND TIC FROM A POLYMERIC PRECURSOR

Hydrolysis of the Ti(O-n-Bu)4/furfuryl alcohol mixture resulted in the formation of a polymeric solid. Pyrolysis of the polymer at 1150-degrees-C under argon yielded metallic, gray TiC. When the pyrolysis was carried out in an atmosphere of anhydrous ammonia, pure TiN containing less than 0.8 wt % carbon was obtained at 1000-degrees-C. The structure and pyrolysis chemistry of the precursor were studied by Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), gas chromatography (GC), elemental analyses, and X-ray diffraction (XRD).
