Description

This paper discusses the reaction between furfuryl alcohol (FuOH) and the hydrolysis product of a mixture of Ti(O-n-Bu)4 and Al(O-sec-Bu)3 (Al:Ti = 1:1) that resulted in the formation of soluble polymeric solids. Pyrolysis of these polymers in argon yielded TiC/Al2O3 composite at 1250 degrees C. When these polymers were pyrolyzed in ammonia, TiN/Al2O3 or TiN/AlN composite was formed. All these composites showed fine microstructure and excellent homogeneity. Furthermore, the structure and pyrolysis chemistry of these polymeric precursors as well as the microstructure of the pyrolysis products were studied by means of FTIR, TGA, XRD, SEM, TEM, STEM, Auger, elemental analyses etc
