Porous Cordierite Synthesized Using Corn Starch

Abstract:

Cordierite (2MgO.2Al₂O₃.5SiO₂) is an advanced ceramic which is popular for its high melting temperature and high resistance to thermal, chemical and corrosion and also low dielectric constant. The use of various structure of cordierite especially porous structure became more popular where its properties can be tailored by controlling the open and closed porosity, cell size distribution and cell morphology. In this study, porous cordierite was synthesized using sol gel method with addition of corn starch (5wt%, 10 wt%, 15 wt% and 20 wt %) as pore forming agent. Characterizations have done using scanning electron microscope (SEM) show that the corn starch used is polyhedral shape with pore size between 6-7 μm. Whereas SEM analysis on sintered sample shows that the porosity obtained ranging from 13 to 46 % with interconnected pores.
