Abstract

A corrosion-resistant electrode is made by treating platinum in a fused bath of an oxidizing salt of potassium e.g. KNO3 or KClO3 whereby a coating of platinum oxide is formed thereon. The platinum body may be pre-coated with Pt black, and then immersed in fused KNO3 at 400 DEG C. for up to 12 or 24 hours, with or without the application of a current of 50 m. Amps. The oxide coating may be predominantly PtO2. The electrode may be used as a standard reference electrode for testing e.g. the corrosion resistance of metal surfaces as described in Specification 1,071,068. (see Heading G1N). Graphs are given showing the potential of the electrode in a range of acid and alkaline liquids.
