Badanie możliwości wykorzystania renianu(VII) tetraaminaniklu(II) wysokiej czystości do wytwarzania proszku stopowego Re-Ni

Abstract

In this paper, a method for preparation of high purity tetraaminenickel(II) perrhenate is presented. This method comprises reacting of a concentrated solution of ammonia water with high purity anhydrous nickel(II) perrhenate(VII). The resulting tetraaminenickel(II) perrhenate is reduced under dissociated ammonia conditions, to obtain Re-Ni alloy powder. The article also provides information on selected physicochemical properties of the produced powder. Such Re-Ni alloy powder can be applied for tungsten heavy alloys production.
