Abstract
Due to zirconia and titania additions carbon‐free fine grained alumina ceramics are produced with superior thermal shock performance. The decomposition of Al2TiO5 in the alumina doped matrix dominates during thermal shock attack and leads to higher strengths in comparison to the as sintered samples after thermal shock. EDX, EBSD, and XRD investigations describe the phase evolution before and after quenching the samples from 950 to 1200 °C in water, respectively.Keywords
