text: It should be particularly noticed in the present invention that by containing at least one crystal selected from the group consisting of spinel, mullite and corundum, the softening temperature which is a factor of the thermal resistance is not only increased, but also the gradient of the softening shrinkage curve from the softening temperature to the melting temperature becomes slow and the melting temperature becomes high and as the result, the softening shrinkage at 1,450° C. becomes less than 10% and the practically satisfactory thermal resistance as the ceramic honeycomb catalyst substrate to be used for the apparatus for purifying exhaust gas of automobile can be obtained.
