ABSTRACT:
The present invention provides an aluminium titanate ceramic composed of, as main crystalline phases, 60-85% of an aluminum titanate phase, 10-25% of a rutile phase, 2-10% of a corundum phase and 2-10% of a mullite phase, wherein the amount of vitreous phase is 5% or less. The aluminum titanate ceramic is superior in both heat cycle durability and casted property.
