【摘要】 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%。更多还原

【Abstract】 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%.更多还原
