摘要
应用特殊方法自行合成了MgS,ZrS_2,MOS_2,WS_2和TiS_2等高熔点硫化物。以MgS+ZrS_2作为固体电解质,以Mo+MoS_2作为参比极,组成定硫探头:Mo|Mo+MOS_2‖MgS+ZrS_2[S]_(Fe)|Mo,在大气气氛下,于1638K,测定了铁水[S]含量。以Mo+MOS_2和W+WS_2作为已知硫分压的参比极和被测极组成定硫探头:Mo|Mo+MoS_2‖MgS+ZrS_2|W+WS_2|Mo,测定了MgS+ZrS_2固体电解质的特征硫分压P_e~＇(s)。试验结果表明,新开发的定硫探头可用于测定铁水[S]含量。
A sulphur sensor of high melting point was developed taking MgS + ZrS2 as solid electrolyte and Mo+MoS2 as reference electrode, i.e.Mo|Mo+MoS2||MgS+ZrS2||[S]Fe|MoThe determination of sulphur content in liquid iron was carried out at 1 638 K (1365℃) in atmosphere. Furthermore, to determine the characteristic partial pressure of sulphur in MgS+ZrS2 solid electrolytes, another sulphur sensor was developed taking Mo + MoS2 as reference electrode and W+WS2 as the electrode to be measured with partial pressure of sulphur given, i.e.Mo|Mo+MoS2||MgS + ZrS2||W+WS2|MoThe experimental results show that both the sensors developed are available to determine [S] content in liquid iron.
