Abstract
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 SiO.sub.2 --Al.sub.2 O.sub.3 --Fe.sub.2 O.sub.3 --TiO.sub.2 --MgO. The mixture consists essentially of 15.7 to 44.0% by weight of SiO.sub.2, 29.8 to 41.0% by weight of Al.sub.2 O.sub.3, 0.9 to 8.3% by weight of Fe.sub.2 O.sub.3, 7.0 to 35.9% by weight of TiO.sub.2 and 4.9 to 16.1% by weight of MgO.
