METHOD FOR PRODUCING INDIUM HYDROXIDE OR COMPOUND CONTAINING INDIUM HYDROXIDE

摘要

A method for producing indium hydroxide or a compound containing indium hydroxide by electrolysis. The purpose of this method is to suppress deterioration of the productivity and deterioration of the quality by performing electrolysis, while setting the electrical conductivity of the electrolyte solution at 10 mS/cm or more, so that indium hydroxide or a compound containing indium hydroxide is precipitated in the electrolyte solution, and then cleaning the thus-precipitated indium hydroxide or compound containing indium hydroxide until the electrical conductivity of the cleaning liquid becomes 1 mS/cm or less.
