在实验室条件下,自制了MgS与TiS_2两种硫化物,组成MgS—2％TiS_2′wt)并经过高温烧结处理。用MgS—2％TiS_2固体电解质组成硫浓差电池: Mo[[S]Fe][MgS-2％TiS_2(wt)]Mo,MoS_2]Mo于1375℃无保护气氛条件下进行了铁液定硫的试验。所测电势E与化学分析的[％S]关系为log[％S]=-0.3694-0.0077E(mV)([％S]:0.013～0.134)。于1375℃下还测试了Cu-Cu2S系的硫位。推算出表征固体电解质电子电导率大小的特征硫分压Pc’对MgS—2％TiS_2来讲为6×10~(-4)pa。引入pe’和硫活度系数f_s对E—[％S]关系进行了修正。
Under laboratory conditions, two kinds of sulfides, MgS-2% TiS_2’wt, were prepared and sintered at high temperature. The sulfur concentration cell was composed of MgS-2% TiS_2 solid electrolyte: Mo [[S] Fe] [MgS-2% TiS_2 (wt)] Mo, MoS_2] Mo under the unprotected atmosphere of 1375 ℃. Test. The measured potential E is related to [% S] of the chemical analysis by log [% S] = -0.3694-0.0077E (mV) ([% S]: 0.013-0.1334). The sulfur sites of the Cu-Cu2S system were also tested at 1375 ° C. The calculated partial pressure of characteristic sulfur Pc ’, which characterizes the electronic conductivity of the solid electrolyte, is 6 × 10 ~ (-4) pa for MgS-2% TiS_2. The introduction of pe ’and sulfur activity coefficient f_s corrects E - [% S].
