Abstract

This paper presents a method for the production of high-purity anhydrous nickel(II) perrhenate. The method comprises sorption of nickel(II) ions from aqueous nickel(II) nitrate solutions, using strongly acidic C160 cation exchange resin, and subsequent elution of sorbed nickel(II) ions using concentrated perrhenic acid solutions. After the neutralization of the resulting rhenium-nickel solutions, hydrated nickel(II) perrhenate is then separated and then dried at 160 °C to obtain the anhydrous form. The resulting compound is reduced in an atmosphere of dissociated ammonia in order to produce a Re-Ni alloy powder. This study provides information on the selected properties of the resulting Re-Ni powder. This powder was used as a starting material for the production of 77W-20Re-3Ni heavy alloys. Microstructure examination results and selected properties of the produced sintered heavy alloys were compared to sintered alloys produced using elemental W, Re, and Ni powders. This study showed that the application of anhydrous nickel(II) perrhenate in the production of 77W-20Re-3Ni results in better properties of the sintered alloys compared to those made from elemental powders.

摘要

本文介绍了一种生产高纯度无水高铼酸镍(II)的方法。该方法包括使用强酸性C160阳离子交换树脂从硝酸镍(II)水溶液中吸附镍(II)离子，随后用浓高铼酸溶液洗脱吸附的镍(II)离子。将所得铼镍溶液中和后，分离出水合高铼酸镍(II)，然后在160°C下干燥以获得无水形式。所得化合物在离解氨气氛中还原以生产Re-Ni合金粉末。本研究提供了所得Re-Ni粉末的选定性能信息。该粉末用作生产77W-20Re-3Ni重合金的原料。将所生产的烧结重合金的微观结构检查结果和选定性能与使用元素W、Re和Ni粉末生产的烧结合金进行了比较。本研究表明，与由元素粉末制成的合金相比，在生产77W-20Re-3Ni时应用无水高铼酸镍(II)可使烧结合金具有更好的性能。
