Polymeric precursors to a wide range of non-oxide ceramics have been synthesized by reacting metallic alkoxides with a range of polyhydric and monohydric alcohols (transesterification). The selection of alcohols controls the shape on the polymer and also the stoichiometry in the coke made by charring the polymer within an inert https://garrettfgecb.wikiap.com/1129580/detailed_notes_on_nano_cuprous_oxide
