水溶液体系制备铀电镀靶

对影响电沉积铀的主要因素进行了试验和讨论,在电沉积法制备铀靶的初期实验中,选用不锈钢作为电沉积铀的靶片,用UO2(NO3)2和(NH4)2C2O4作为镀液,pH值为2~3。对影响电沉积铀的主要因素进行了试验和讨论,并用分光光度法分析了电镀残液中的铀含量,最终制得的铀靶的沉积厚度达到8~10mg/cm2,镀层牢固、均匀,电镀效率大于80%。

Preparation of Uranium Electrodeposite Target in Aqueous System (In Chinese)

The main factors affecting uranium electrodeposition were tested and discussed. In the primary experiment about preparation of uranium isotopic target by electrodeposition, a stainless steel disk has been chosen as the target material, the electrolytic bath is comprised of UO_ 2 (NO_ 3 )_ 2 and (NH_ 4 )_ 2 C_ 2 O_ 4 , which has been adjusted to a pH of 2~3. Composition of the lost electrolytic bath was analysed by spectrophotometer. The thickness of resulting film is about 8~10 mg/cm~ 2 , the target having a thin, continuous, uniform layer of uranium, and its electrodeposited rate is more than 80%.
