Polymeric precursors to an array of non-oxide ceramics have been synthesized by reacting metal alkoxides with A selection of polyhydric and monohydric alcohols (transesterification). The selection of alcohols controls the shape from the polymer plus the stoichiometry of the coke produced by charring the polymer within an inert ambiance.
