Abstract

Polymers that can be easily processed into fibers, films, or bodies are excellent precursors for ceramics with useful morphologies. The ideal preceramic polymer not only has proper physical properties (e.g. solubility or fusibility) for processibility but also decomposes at low temperature with high ceramic yield. One possibility for such precursors for yttria are yttrium oxycarboxylates. The preparation of such polymers from YOC1 has been investigated and several compounds with useful physical properties have been discovered. These include a methanol-soluble yttrium oxycarboxylate, (CH3OCH2CH2OCH2CO2YO)n a liquid yttrium tricarboxylate, (CH3OCH2CH2OCH2CO2)3Y, and a method for preparing very concentrated yttrium mixed acetate and formate sols.
