Embodiment 1
[0018] Preparation of the composition:
[0019] Add deionized water to the rhenium-plating tank, heat it to 40-50°C, weigh potassium rhenate, ammonium sulfate, and nickel sulfate and pour them into the rhenium-plating tank in sequence, stir to dissolve them completely, and filter. Each liter of deionized aqueous solution contains 10 g of potassium rhenate, 3 g of ammonium sulfate, and 40 g of nickel sulfate.
Embodiment 2
[0021] Except that every liter of deionized aqueous solution contains 20 g of potassium rhenate, 6 g of ammonium sulfate, and 60 g of nickel sulfate, the rest are the same as in Example 1.
Embodiment 3
[0023] Except that every liter of deionized aqueous solution contains 30 g of potassium rhenate, 9 g of ammonium sulfate, and 80 g of nickel sulfate, the rest are the same as in Example 1.
