Abstract
Catalyst carriers made of cordierite honeycomb structures having low thermal expansion, porosities of not exceeding 30%, high strengths and thin partition walls with high cell density or low cell density are provided by using very fine particles of kaoline and talc which are considered heretofore disadvantageous for producing such catalyst carriers. The catalyst carriers are useful in a broader use field than conventional ones, particularly as catalyst carriers for purifying exhaust gases exited from automobile engines.
