Characterisation of (17)O-enriched alumina from a new hydrothermal preparation.
A novel method for the hydrothermal synthesis of (17)O-enriched alpha-Al(2)O(3) is presented. Its advantage compared to commonly used methods is that Al(2)O(3) is directly produced from metallic Al and (17)O-enriched H(2)O without formation of intermediate Al-hydroxide phases that require subsequent dehydration. This is a much more efficient use of the (17)O label as the Al(2)O(3) has similar (17)O enrichment level as the H(2)O initially used.
