“…The mass change data for CaO indicate that there was little interaction with lithium at 400°C (Table 1), which is in agreement with previous experimental work [1,2] and thermodynamic calculations [3,4,7]. However, at 500±800°C, signi®cant mass losses of CaO were recorded that generally increased with temperature (Table 1).…”

“…It has been noted that thermodynamic calculations [3,4,7] indicate CaO and AlN should not be reduced by lithium and, therefore, should be good candidate MHD coating materials at the temperatures of interest. However, the present results for polycrystalline CaO and AlN + 0.04%Y do not con®rm these predictions.…”

“…Thermodynamic calculations indicate that two of the promising candidates are AlN and CaO [3,4,7]. Initial experimental work was conducted on bulk ceramics to determine maximum-use temperatures of AlN and CaO.…”

Two candidate materials for insulating coatings in a lithium-cooled fusion reactor have been exposed to lithium in 1000 h isothermal tests from 400±800°C to determine their maximum compatibility temperature. Bulk samples of AlN 5 wt%Y 2 O 3 showed signi®cant mass loss at 600°C and higher temperatures. The amount of attack was reduced when AlN 0X04 wt%Y was tested. Characterization by Auger spectroscopy of a AlN 0X04 wt%Y specimen exposed at 600°C indicated the possibility of a lithium aluminate compound formation. Bulk, polycrystalline specimens of CaO (99.9% purity) showed mass losses above 500°C indicating a possible dissolution problem that had not been observed in previous short-term screening tests and is not predicted based on thermodynamic calculations. Doping of the lithium with oxygen (in the case of CaO) did not appear eective in reducing the mass loss at 600°C. Ó

“…It is evident from thermodynamics and experimental data that only Er 2 O 3 , BeO, Y 2 O 3 , Si 3 N 4 , BN, AlN, ThO 2 and MgO can be relatively stable to lithium and that is true at relatively high concentration of nonmetallic impurities in lithium [10,12,16,17]. Since lithium oxide is one of the most thermodynamic stable compounds unlike nitride, the ceramic materials based on nitrides are more preferable for their use in the lithium medium.…”
