Description
The Electrodeposition of Sb-Te alloy was carried out in AlCl3-NaCl-KCl molten salt containing SbCl3 and TeCl4 at 423 K by constant potential electrolysis. The voltammogram on a glassy carbon (GC) electrode in a melt containing 1.0×10−2 kmol m−3 SbCl3 and 1.0×10−2 kmol/m3 TeCl4 revealed the cathodic current waves at 1.5, 1.1, and 0.9 V vs. Al/Al(III). A stable Sb-Te alloy deposit was obtained at 0.85 V in the melt containing SbCl3 and TeCl4. At the higher concentration ratio of the Sb(III) to (Sb(III) + Te(IV)), a good linear relation was found between the atomic ratio of Sb in the deposit and the concentration ratio of Sb (III) in the melt. The Sb-Te alloy deposit of atomic ratio of 38:62% which was assume to be suitable for a thermoelectric device was obtained with the molten salt containing 7.0×10−3 kmol/m3 SbCl3 and 1.0×10−2 kmol/m3 TeCl4. The XRD pattern of the deposit corresponds to that of Sb2Te3 intermetallic compound. The deposit had homogeneous disk-like granule with the disk size of about 10 μm.
