Abstract
Some results and problems associated with the known chemistry of cesium and iodine in the presence of Zr/ZrO2 at 400-600°C and under anaerobic conditions are described and discussed. These aspects include 1. (1) the recently synthesized cesium zirconates Cs2ZrO3 and Cs4ZrO4 and some of their thermal and hydrolytic properties 2. (2) the demonstration that the supposedly stable CsI reacts with ZrO2 at 400-700°C to form Cs2ZrO3 and ZrI4 (as Cs2ZrI6) and its implications regarding cesium and iodine distributions 3. (3) present knowledge of binary zirconium iodides, their contamination reactions, and the limited inhibition of the reduction of ZrI4 by metal provided by static ZrO2 films 4. (4) newly discovered ternary and quaternary zirconium iodides that are obtained in the presence of many common impurity atoms and, when prsesent, CsI (e.g., Zr6I12C, CsZr6I14C, Zr6I14Fe), the ease with which some of those form at least as low as 450°C, and the complications these and related new phases provide.
