Abstract
Recent advances in modem technology have created an increasing demand for ultrahigh purity metals. For example, ultra-high purity copper could be used as a bonding wire and interconnector in integrated circuits or as a superconductor stabilizing material, highfield magnet, besides its use in cryogenics and ultra-high vacuum technology.1 Iron, together with chromium and manganese, is used in the production of special magnetooptical materials for digital recording. Development of new opto-electronic devices based on the application of β-FeSi2 also demands extreme purification of the constituent elements. The use of ultra-high purity manganese and chromium in semiconductor technology is evolving. Ultra-pure zinc has a major significance in the propenies of ZnSe compound used as semiconductor3 materials.
