Title:
ELECTROLYTIC ELECTRODE BASE BODY, ELECTROLYTIC ELECTRODE AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP3212334
Kind Code:
B2
Abstract:
PURPOSE: To provide an electrode base body capable of being used for the electrolysis with the polarities reversed and in the electrolyte contg. fluorine compds. and capable of carrying out electrolysis with a relatively low ohmic loss and an electrode using the base body.
CONSTITUTION: An oxide layer having a nonstoichiometric composition consisting of at least one kind of metal among titanium, tantalum and niobium and having 10 to 200μm thickness is formed on a conductive base body. The oxide layer is intrinsically resistant to reverse electrolysis and fluorine compds., conductivity is imparted by the free electron resulting from lattice defect, and a desired electrode, etc., are provided. An intermediate thin layer contg. titanium oxide, tantalum oxide and platinum is formed between the electrode base body and an electrode activating material. The infiltration of the liberated oxygen into the conductive base body is suppressed by the platiunm in the intermediate thin layer, the catalytic activity of platinum is controlled by the titanium oxide, etc., and the life of the electrode is prolonged.
