Abstract

The aim of this study is focused on the elaboration of new bio-based alumina concentrated suspensions with rheological properties adapted to the tape casting process and with low environmental impact. Natural polymers extracted from plants were identified as promising candidates in order to substitute the classical organic additives. Aqueous suspensions were prepared from these bio-polymer additives. Finally, the rheological properties of the suspensions and the mechanical properties of the green and sintered tapes were determined in relation with the nature of bio-polymer additives.
