<p>PURPOSE:To recover a metal vapor deposit at a low cost, by allowing a low-m. p. liquid metal to flow on the metal vapor deposit so as to melt the metal vapor deposit in the liquid metal and by recovering the metal vapor deposit in the liquid metal. CONSTITUTION:A high-m.p. metal vapor current 3 (e.g., uranium, etc.) is prepared from a mixture 2 in a crucible 1 in a vacuum vessel and then the high-m. p. metal 5 is vapor-deposited onto a vapor-deposition substrate 4. When the low-m.p. liquid metal 7 (e.g., mercury) capable of melting the high-m.p. metal 5 is allowed to flow on the above high-m.p. metal 5, the high-m.p. metal 5 can be recovered into a vessel 8 by means of the low-m.p. liquid metal 7. Further, the low-m.p. liquid metal 7 is used by circulation by the use of a pump 9. In this way, the high-m.p. metal vapor deposit 5 recovered in the liquid metal 7 can be easily recovered by evaporating the liquid metal 7.</p> |
