Twenty pure metals were considered as potential candidates for first wall coatings of ICF reactor chambers. Seven were found to merit further consideration based on the results of computer code calculations of figures-of-merit. The seven are rhenium, iridium, molybdenum, chromium, tungsten, tantalum, and niobium (listed in order of decreasing values of figures-of-merit). The calculations are based on mechanical, thermal, and vacuum vaporization engineering constraints. A number of alloys of these seven metals are suggested as additional candidates.
