This study aims at i) studying the rhelogical behavior of suspensions based on kaolin and halloysite, ii) shaping textured ceramics by tape-casting and (iii) determining stress to rupture values after different thermal treatments. Main results revealed that 0.2 mass% is the suitable amount for the best dispersion. Moreover, halloysite nanotubes increase significantly mechanical properties after 1200°C.
