The starch consolidation casting (SCC) method was used for the preparation of porous structure ceramic based on partially stabilized ZrO2 with other oxides such as MgO and Al2O3 with the addition of tapioca and potato starch as a binder and pore-forming agents. For casting purpose, three impermeable plastic moulds were designed and manufactured with different sizes and shapes depending on the shape and size of the required samples. The method is based on the fact that after being heated to about 80°C, starch may swell and absorb water from aqueous ceramic solutions. The process's simplicity, the ability to create complicated shapes using different moulds, and the inexpensive cost of the necessary processing tools and materials are its main benefits.
