#CMT# #/CMT# The electrode (16) comprises an electrode substrate (17) having a coating (19) with polycrystalline diamond material or diamond-like carbon and a contact layer (20), which bears the coating and consists of non-metallic electrically conducting material. The electrode substrate consists of a base body (18) made of glass carbon material. The contact layer has a pore size reduced against the base body, and has a polished surface with a roughness (R a) of less than 15 mu m. The contact layer is formed by a post-processed surface of the base body, and is made of silicon carbide coating. #CMT# : #/CMT# The electrode (16) comprises an electrode substrate (17) having a coating (19) with polycrystalline diamond material or diamond-like carbon and a contact layer (20), which bears the coating and consists of non-metallic electrically conducting material. The electrode substrate consists of a base body (18) made of glass carbon material. The contact layer has a pore size reduced against the base body, and has a polished surface with a roughness (R a) of less than 15 mu m. The contact layer is formed by a post-processed surface of the base body, and is made of silicon carbide coating applied on the base body, where the carbide is doped with a semiconductor for obtaining the electrical conductivity of the coating and is doped with boron and nitrogen. The carbon material of the base body consists of graphite with a density of 1.6-1.85 g/cm 3>. The layer thickness of the coating is less than 150 mu m. The layer thickness of the contact layer is 0.2-100 mu m. #CMT#USE : #/CMT# Electrode for electrolysis. #CMT#ADVANTAGE : #/CMT# The electrode can be efficiently manufactured with high reliability and increased durability without the formation of microcracks and defects. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a schematic representation of an electrode. 16 : Electrode 17 : Electrode substrate 18 : Base body 19 : Coating 20 : Contact layer. |
