| description | In this study, ceramic foams were produced using starch consolidation casting method.
This research focused on the preparation of alumina-based ceramic foam by using corn starch as a
pore-forming agent. Preparation of alumina based ceramic foam is studied to observe the effect of
the addition of corn starch on its physical, mechanical and morphological properties. The
composition of the suspension used included 58-64 wt.% alumina, 55 wt.% deionised water and
other materials, such as silica and polyethylene glycol (PEG), were used as additive and dispersing
agent respectively. The ceramic foam gave a linear shrinkage from 1.07% to 3.39%. The obtained
flexural strength was between 0.594 and 1.996 MPa. The average total porosity ranged from
54.05% to 70.70%. This study found that the suitable amount of corn starch in alumina foam is
4 wt.% because the resulting porosity values and flexural strength are appropriate for ceramic
foams. |
