Ceramic filters have been widely is in the filtration and separation processes technology. Due to advantage of the ceramic properties, the ceramic filter can be used from water filtration, molten steel separation even to petrochemical filtration or separation applications. In this study, local silica is selected for the preparation of the fabrication of ceramic filter. It is also to study the suitability of the local silica as the alternative materials for the current alumina filter. Two selected formulation of silica with the characteristic particle sizes distribution and binders were formulated and mixed in a z-blade mixer for 3h respectively. The mixer was extruded using the deairing pugmill. The extrudate was cut into 80mm x 15mm x 10mm and dried. Then, the samples were fired at 2oCmin-1 to maximum temperature from 1000oC to 1300oC and held for 30min before cooling. Sintered samples were characterized for the density, microstructures, porosity and flexural strength and the results are presented.
