ABSTRACT:
Disclosed is an electrode for use in electrochemical processes wherein a metal substrate made of a valve metal mesh such as titanium carries a semiconductive intermediate coating consisting of tin and antimony oxides laid down upon the valve metal mesh in a series of layers and an electrocatalytically active top coating of an oxide of manganese, applied in a series of layers or by electroplating and subsequently baked in an oxidizing atmosphere at a temperature in the range of 380.degree. to 420.degree. C.
