| Research Abstract |
Object 1 ; (1998) Electrochemical discussion of the condition that make electro-deposited Bi-Sb alloys using potensiostat. In this experiments, the possibility of alloy-deposition of Bi-Sb binary system, and the adequate composition of the bath were determined under strong hydrochloride acid condition.
(1) bath temperature ; 40-50℃ was best.
(2) pH of the bath ; the best of the range of the pH was -2〜0.
(3) bath composition ; HC1 (100-300ml/l), BiClィイD23ィエD2 (80-200g/l), SbClィイD23ィエD2 (1-80g/l) were the best composition range to form Bi-Sb alloy deposits.
(4) Current density of electro-deposition ; 1〜3A/dmィイD12ィエD1 were most suitable range to form the good crystal and well big size.
