Electrochemical Studies of Lead Telluride Behavior in Acidic Nitrate Solutions

Electrochemical Studies of Lead Telluride Behavior in Acidic Nitrate Solutions

Electrochemistry of lead telluride stationary electrode was studied in nitric acid solutions of pH 1.5-3.0. E-pH diagram for Pb-Te-H2O system was calculated. Results of cyclic voltammetry of Pb, Te and PbTe were discussed in correlation with thermodynamic predictions. Anodic dissolution of PbTe elec...
