Electrochemical Corrosion Study of Silicon in Potassium Formate Solutions

Mingzhang Wang, Dynalene Inc; S. Mohapatra, Dynalene Inc.

Potassium formate aqueous solutions have been considered as heat transfer fluids or coolants for electronics cooling applications. Electrochemical corrosion tests were performed on high purity silicon specimens in 42% potassium formate solutions between 25°C and 75°C, with a magnetic stirring rate of 400 RPM. Open circuit potentials, corrosion potentials, and corrosion rates were measured. The temperature dependence of corrosion rates was assessed. The effect of a corrosion inhibitor package was also investigated.
