In this paper, pre-gelling starch was used to consolidate alumina-dense ceramic suspensions. The colloidal processing of the ceramic was prepared with alumina and commercial potato starch, and slips were prepared with 55 vol% of solids and 0.5 wt.% of starch. This small amount of starch was possible because of a previous pre-gelling starch treatment, resulting in more homogeneous suspensions and particles smaller than starch granules. Additionally, sucrose was also used as a dispersion aid. After sintering, the samples were analysed according to their mechanical properties. These processes produced ceramics with a 93% relative density, 325 MPa flexural strength, and a Weibull module whose value was m = 10, maintaining the capacity of this process to produce complex geometric shaped ceramics.
