説明

Potentiostatic electrodeposition behavior of dendritic copper from acidic copper(I) chloride (cuprous chloride) bath containing sodium chloride and sodium bromide was investigated. The morphology, or appearance, of copper dendrite and sodium content in the dendrite as an impurity were both influenced by deposition potential (0 to -150 mV vs. SHE), bath temperature (R.T. to 60°C) or Cu(I)-ion concentration (0.35 to 1.14 mol dm-3) investigated, while current efficiency for the deposition was 99% or more irrespective of the deposition condition investigated. Bath pH did not affect the deposition behavior within pH 0 to 2. Bath temperature was found to be the most important factor influencing the deposition current. The deposition behaviors were discussed with the potential-pH diagram of the Cu-Cl-H2O system.
