Abstract
Electrochemical properties of the intermetallic compound UPd3 in 0.5–8 M HNO3 solutions were studied by linear voltammetry. In 0.5–2 M HNO3 solutions, the UPd3 surface is in the passive state. At HNO3 concentrations exceeding 4 M, the alloy passivation was not observed. The previously unknown electrochemical characteristics of UPd3 in nitric acid solutions were obtained using the Tafel equation. The values of Е(i = 0) and vcorr increased from 39 mV and 38 μg cm–2 h–1 in 0.5 M HNO3 to 821 mV and 11 mg cm–2 h–1 in 8 M HNO3, respectively. Dissolution experiments have shown that UPd3 can dissolve in HNO3 solutions of concentration exceeding 4 M at room temperature. In 8 M HNO3, the dissolution rate can reach 17 mg cm–2 h–1 at 25°С, with the dissolution being virtually equimolar and accelerating with time.
