Mullite formation was observed at a 100°C higher temperature when diphasic gels were formed by mixing aged polymeric sols containing about 2 nm in diameter boehmite species. These relatively low mullite formation temperatures were attributed to the nanoscale sizes of the polymeric species of the two amorphous phases present in the diphasic gels.eninfo:eu-repo/semantics/openAccessDiphasic gelMullite crystallizationUnsupported ceramic membraneSol-GelPolymersArticle2-s2.0-7995460069710.1007/s10971-010-2347-x
