Some initial runs were made to test the concept of maintaining melt stoichiometry by forming it within a sealed crucible. These runs were hindered by weld problems associated with the alloying of Iridium with Vanadium metal formed by the reduction of the YVO4 melt. Changes in welding techniques and furnace design- will be made to alleviate this problem.
