Kesan rawatan haba terhadap mikrostruktur katod berliang Ag2O3-Bi2O3 di atas substrat keluli kalis karat yang disediakan dengan kaedah pengecatan sluri

The influence of thermal treatment on the microstructure of Ag2O3-Bi2O3 porous cathode on stainless steel substrates has been investigated. The composite cathode material has been successfully deposited on the substrates by the slurry painting method. The cathode was later thermally treated at diffe...
