Effect of sintering technology on Ag/AgCl electrode potential stability

The effects of sintering technologies on the stability of electrode potential were researched.Four kinds of electrodes,which were respectively sintered to 380℃,420℃ and 450℃ by two heating methods(direct heating and phase-type heating) were prepared.Their surface morphologies,metallographic structures and the electrode potentials were analyzed to compare the different sintering technologies.The results show that the electrodes sintered to 380℃ by phase-type heating-insulation method have the best surface evenness and stability of potential.
