<p>A process for producing a honeycomb structure, comprising the steps of: providing a substrate having cell walls in a honeycomb form and comprising SiO2, Al2O3 and MgO as the main chemical components, applying to said substrate a mixture of a component for lowering the cordierite crystal phase crystallization temperature of said substrate with a liquid medium, and firing said substrate with said mixture applied to form a honeycomb structure comprising a crystalline cordierite phase, said crystalline cordierite phase comprising 42 - 56% by mass of SiO2 30 - 42% by mass of Al2O3 and 12 - 18% by mass of MgO as the main chemical components. <IMAGE></p> |
