Preparation of self-supporting, metallic Hf targets from isotopically enriched HfO2
- 1. Sektion Physik, Universitaet Muenchen, Garching (Germany)
Description
Bomb reduction of HfF4 with Na results in Hf metal sufficiently pure to prepare self-supporting Hf targets of 100-350 μg cm-2 thickness by high vacuum sputter deposition. A necessary condition for the success of the procedure is the capability to convert HfO2, the standard chemical inventory form of enriched Hf isotopes, into HfF4, which is free from oxyfluoride admixtures. This is also described in some detail. Targets of the isotopes 176Hf, 177Hf, 178Hf, 179Hf and 180Hf have been prepared by this method. (orig.)
