摘要：
Er(2)O(3) is one promising material for use as an insulating coating in a liquid lithium blanket system. In this study, corrosion of bulk Er(2)O(3) in Li with high or low O concentrations was investigated at 600 degrees C. The tests revealed that the corrosion reaction is accelerated under high O condition and suppressed in low O concentration. From these results we assumed the corrosion reaction and tested with more precise condition. The Er(2)O(3) bulk specimen corroded significantly in Li with more than 300 ppm O. Control of O concentration is essential for a Li blanket system with an Er(2)O(3) coating.
