摘　　要：分别采用3种温度(380℃、420℃和450℃)、2种升温方式(直接升温和阶段性保温升温)制备电极,并通过对电极表面微观形貌和金相结构的观察以及电极电位的检测分析方法,比较了不同烧结工艺的电极性能。实验结果表明:烧结后的电极体积略微膨胀,采用380℃阶段性保温升温方式烧结的电极具有更好的表面均匀性以及电位稳定性。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.
