Adaption of a smelting furnace to immersion experiments of solid metals in liquid metals

The adaption of existing smelting furnace, to immersion experiments of solid metals in liquid metals, is described. The modifications include a Wilson seal, a stainless-steel feed-through, to which a molybdenum rod is adjoined with a metal sheet made in the form of a cylinder or a scoop attached to the latter by means of a tantalum wire. The metal sheet is immersed, in a controlled way, in the liquid metal which is contained in a magnesia-stabilized zirconia crucible held in a protective graphite crucible. The results of a few immersion experiments are given. (Author)
