A purpose of the present study is to investigate the compatibility of SiC/SiC composite material and AlN ceramics with liquid metals. Corrosion behavior of materials could be affected by non-metallic impurities like nitrogen in liquid lithium. Another purpose of the present study is to control the concentration of nitrogen impurity by using getter materials and to study the effect of getter materials on compatibility with AlN. At 700K, all of the SiC/SiC specimens, except high purity specimen, were entirely broken down in liquid lithium. Even in this high purity specimen, many cracks were observed on the surface. On the other hand, in the case of SiC/SiC with Li17Pb83 at 773K, all of the specimens were not corroded. At 673K, impurity levels in AlN were changed in the case immersed in liquid lithium with getter materials. At 823K, impurities in AlN were attacked by lithium and the surface of it was locally peeled off. It was also observed that the getter material captured nitrogen.
