Polymeric precursors to a wide array of non-oxide ceramics happen to be synthesized by reacting steel alkoxides with A selection of polyhydric and monohydric alcohols (transesterification). The selection of alcohols controls the shape of the polymer along with the stoichiometry of the coke produced by charring the polymer in an inert atmosphere.
