Title:
ELECTRODE FOR INDUSTRIAL ELECTROLYTIC PROCESS
Document Type and Number:
WIPO Patent Application WO/2023/286392
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an electrode having high durability and a lower manufacturing cost; and a manufacturing method therefor. This electrode includes a mixed metal oxide-containing coating on a valve metal substrate with an intermediate layer therebetween, the intermediate layer containing an alloy containing a titanium component and a tantalum component, wherein: the molar ratios of metal elements in the mixed metal oxide are 35-48% for the total of an iridium element and a ruthenium element, 45-60% for a tin element, and 3-9% for a tantalum element; and the molar ratio of the iridium element with respect to the total of the iridium element and the ruthenium element in the mixed metal oxide is 32-60%.
