MANUFACTURING METHOD OF A DIMENSIONAL STABLE ANODE

摘要

An insoluble oxide electrode manufacturing method which improves productivity considerably by simplifying the manufacturing process and reducing the entire manufacturing process time, and can coat an oxide layer on a matrix such that the oxide layer has an uniform and compact structure is provided. In a manufacturing method of an insoluble oxide electrode, comprising a pretreatment process of properly imparting roughness to a surface of a matrix by etching or sand blasting, a process of coating the surface of the matrix with a metal chloride, a firing process, and a cooling process, the method is characterized in that the process of coating the surface of the matrix with a metal chloride is performed by using the matrix dipped into an aqueous RuCl3 or IrCl3 solution as a cathode and using a prefabricated insoluble oxide electrode as an anode, and applying a DC power source to the cathode and the anode at a current density of 5 to 20 mA/cm^2 for 30 minutes to 2 hours. The matrix is titanium.
