Title:
METHOD FOR ELECTRODEPOSITING METAL
Document Type and Number:
WIPO Patent Application WO/2007/029663
Kind Code:
A1
Abstract:
Disclosed is a method for electrodepositing a metal wherein a molten salt is used. This method enables to easily electrodeposit various metals including high melting point metals and rare earth metals. Specifically disclosed is a method for electrodepositing a metal wherein a quaternary ammonium halide molten salt represented by the general formula (I) below (wherein R1, R2, R3 and R4 independently represent an optionally substituted alkyl group having 1-12 carbon atoms or an optionally substituted cycloalkyl group having 5-7 carbon atoms, and X- represents a halide anion as a counter ion for a quaternary ammonium cation) and/or a pyrrolidinium halide molten salt represented by the general formula (II) below (wherein R5 and R6 independently represent an optionally substituted alkyl group having 1-12 carbon atoms or an optionally substituted cycloalkyl group having 5-7 carbon atoms, and X- represents a halide anion as a counter ion for a pyrrolidinium cation) are used at an electrodeposition temperature of 100-200°C.
