ABSTRACT:
A ceramic material for a honeycomb structure is prepared from a mixture of raw materials comprising per 100 parts by weight of the mixture 40 to 90 parts by weight of cordierite powder and 10 to 60 parts by weight of crystalline glass powder having a crystalline phase consisting mainly of a solid solution of .beta.-spodumene. The mixture consists essentially of 51.5 to 64.4% by weight of siO.sub.2, 24.8 to 33.7% by weight of Al.sub.2 O.sub.3, 5.5 to 12.4% by weight of MgO and 0.4 to 2.7% by weight of Li.sub.2 O. It may further contain up to 5.1% by weight of TiO.sub.2 and up to 1.8% by weight of ZrO.sub.2.
