There are very few demonstrated applications of ceramic precursor technology. Here, we describe two new applications of known ceramic precursors, thin film deposition and the fabrication of functionally gradient materials [FGM]. To demonstrate the thin film deposition, we prepared titanium nitride film on an alumina substrate using (CH3)3SiNHTiCl3 precursor by a single dipcoat-fire cycle. The fabrication of copper and aluminum based FGMs was demonstrated using Nicalon® fiber polycarbosilane and poly(methylsilane) precursors as binders and in situ sources of ceramics.
