Abstract

Rhenium, a relatively new and unknown metal, is inherently rare and probably will continue to be expensive. However, at least a few thousand pounds can be readily obtained yearly as a by-product from molybdenum concentrates. Its extremely high melting point and good metal properties indicate a growing use for those applications where a relatively high cost can be tolerated. Uses in the electronics industry, as an electrical contact material, alloyed with tungsten and with molybdenum, and for high temperature thermocouples are among potential industrial applications.
