ABSTRACTPolycrystalline magnesium aluminate spinel (MgAl2O4) and Al23O27 N5 (ALON) were irradiated with 4 MeV Ar+ ions to doses from 0.5 to 6 displacements per atom (dpa) at a temperature of 1070K and subsequently examined using transmission electron microscopy. Faulted dislocation loops were found in both materials, although their habit planes ({110} and {111} respectively) and Burgers vectors (a/4 <110> and a/6 <111>) differ. Cavities were found in spinel but not in ALON. Both materials exhibited a similar, low, degree of radiation damage and we conclude that polycrystalline ALON is a good potential reactor window material.

Specimens were prepared using iron-rich magnesia (3~1 mm、≤1 mm) and high purity magnesia (≤0.088 mm) as the main starting materials, adding tabular alumina at different size (3~2、2~1、≤1 mm) and content:3%、6%、9%、12%、15% to discover the influence of tabular alumina on sample performance. Phase composition and microstructure were also analyzed. The results show that specimen with content of 6% of corundum possessed the best comprehensive performance:apparent porosity 17%, bulk density 2.95 g·cm-3, cold crushing strength 74 MPa, refractoriness under load 1700 °C, heat shock resistance of up to 18 times. The formations of magnesium aluminate spinel and hercynite solid solution were enhanced by Fe ion at high temperatures in the iron-rich magnesia-corundum system at the presence of iron oxides, which are able to largely dissolved in periclase.
