ANTIMONY
Natural Abundance, Stable Isobars Sb 121, 57.25%, aTe123 Sb 123, 42.75% Antimony triiodide, antimony trisulfide, antimony trioxide, and antimony metal have been used as charge material in the separation of antimony isotopes. Both the oxide and metal are satisfactory; however, more stable calutron operations are obtained when using the metal. The usual charge consists of 300 g Sb metal in a style C-16 graphite charge bottle. Granulated Sb metal can be obtained from commercial sources and is satisfactory as a calutron charge material without further processing. Antimony and its compounds are acute toxicants. Extreme care should be taken to eliminate the possibility of ingestion or inhalation. The use of a good fume hood or respirator, rubber gloves, and observance of good hygienic practices are recommended when handling antimony and its compounds. aTe123, natural abundance 0.87%, is radioactive with a half-life of > 1014 years. |
