Electrodeposition of Bi-Sb-Te Alloys by Pulse Electrolysis in AlCl3-NaCl-KCl Molten Salt

Year: 2009

Type: article

Abstract: The electrodeposition of Sb-Bi-Te alloy in AlCl3-NaCl-KCl molten salt containing SbCl3, BiCl3, and TeCl4 at 423 K was carried out under constant potential control and potential pulse control in the melt. The electrodeposition results show that the SbCl3 concentration is effective to control the composition of Bi-Sb-Te ternary alloy. The electrodeposited Bi0.5Sb1.5Te3 by pulse electrolysis with frequency=100 Hz and D. R. (Duty Ratio)=75%, had good crystallinity and the preferential orientation of the electrodeposit was the (110) plane in this electrodeposition experiments. The electrodeposit had homogeneous disk-like granules. The power factor of the electrodeposit was calculated as 3×10−5 Wm−1 K−2 from the Seebeck coefficient and the electrical conductivity.
