In this study, cordierite was prepared by glass-route method using Si02, A1203 and MgO as raw materials. Cordierite powder produced was then used to fabricate 3-D porous cordierite using gel casting method using different amount of GRF (2.5, 4.0 and 6.0g) and dried egg white (DEW) (1.5, 2.5 and 4.0g) as binder to observed their effect on the strength of 3-D porous cordierite produced. Results show that the decreasing of solid loading shows decreasing of density, increasing of porosity and decreasing of strength of 3-d porous cordierite. While, decreasing of dispersant amount shows decreasing of density, increasing of porosity and decreasing of strength. The optimum properties of 3-D porous cordierite obtained with the addition of 4.0 g starch (GRF) , having 0.5 g/cm3 density, 74 % porosity, 9.13 MPa compressive strength and 4.07 MPa MOR. Generally, results obtained shows that 3-D porous cordierite produced from this study was possible to become alternative materials for filter application.
