An aluminum titanate structure produced by using a starting material containing at least an aluminum titanate cullet (AT cullet) whose aluminum titanate proportion is 90% or more, shaping the starting material and sintering the shaped material, comprises, as a main phase, crystal grains having an aspect ratio of 1.6 or more and an average projected diameter of 5-10 mu m. Said structure has excellent thermal shock resistance and high actual break strain, and is preferably used in casting with metal(s) to produce a port liner, etc. |
