The corrosion behavior of lithium vapor on AlN composites with three different compositions prepared via plasma assisted sintering in lithium vapor was studied at 550°C. Depending upon the SEM&XRD observations, it is inferred that both MgO and Y 2 O 3 have influences on the corrosion resistance of the composites. The presence of Y 2 O 3 in the composites can adjust the distribution of precipitation phase on the sample surface while the increased content of MgO contributes to a relatively weak corrosion resistance. Among the three composites, the sample with AlN-25%wt MgO-3%wt Y 2 O 3 has the worst corrosion ability.
