Porous cordierite is among the special porous ceramic due to its extensive properties. In this research, porous cordierite was fabricated through gelcasting method. A mixture of raw materials (SiO2, Al2O3 and MgO) was melted at 1550 °C followed by quenching in water to produce a glass. Then the formed glass powder were milled for 1, 3, 5, 7 and 9 hours to obtain various particle sizes of cordierite powder. Cordierite powder produced was then used to prepare 3-D porous cordierite ceramic using gelcasting method. The cordierite pellets were characterized. Surface morphology was analysed via Scanning Electron Microscope (SEM) to observe the pore structure of porous cordierite formed from powder with various particle sizes.
