A ceramic material for a honeycomb structure is formed from a mixture of raw materials comprising, per 100 parts by weight of the mixture, 20 to 80 parts by weight of cordierite powder and 20 to 80 parts by weight of powder having a crystalline phase consisting mainly of a solid solution of SiO2-Al2O3-Fe2O3-TiO2-MgO. The mixture consists essentially of 15.7 to 44.0% by weight of SiO2, 29.8 to 41.0% by weight of Al2O3, 0.9 to 8.3% by weight of Fe2O3, 7.0 to 35.9% by weight of TiO2 and 4.9 to 16.1% by weight of MgO. |
