The investigation of an AZT ceramic in comparison with a pure alumina ceramic by means of wedge splitting tests with in-situ crack growth observation was the topic of previous work in cooperation with “Forschungszentrum Juelich”, Germany.7 Growth and opening displacement of the main crack was accompanied in the AZT ceramic by pronounced microcracking, branching and bridging processes. The thermal shock parameter R’’’’, which is a measure of the resistance against crack propagation under thermal shock loading8, was determined. The values predicted a higher thermal shock resistance of the AZT ceramic compared with pure Al2O3.7 As described in another previous publication9, different thermal expansion coefficients of the phases formed during sintering contribute to the high resistance of AZT ceramics against thermal shock. The focus of the present paper is on Al2O3-rich magnesium aluminate spinel, a widely used refractory material, which was modified by the addition of aluminum titanate. Initially, typical results of thermal shock experiments on AZT ceramic are shown for the purpose of comparison. |

| 一个与纯氧化铝陶瓷相比的AZT陶瓷的研究，借助于具有原位观察裂纹增长的楔入劈拉试验，这是与“德国尤里希研究中心”合作的以前工作的主题【7】。主要裂纹的增长和张开(开口)位移相伴于AZT陶瓷的明显微裂纹，裂纹分支和搭桥（衔接）过程。确定了热震(冲击)参数R”“，这是一个衡量热冲击(震)载荷下的（抵）抗裂纹扩展。【8】AZT陶瓷抗热震性的预测值相比于纯Al2O3的更高。【7】如另一个前期文献【9】所描述，烧结过程中所形成相的不同热膨胀系数有助于AZT陶瓷耐热冲击的高阻抗。本文的重点是有关富Al2O3铝酸镁尖晶石，一种广泛使用的耐火材料，它通过添加钛酸铝而改性。首先，展示以比较为目的的AZT陶瓷的热冲击实验典型结果(值)。 |
