Abstract Large amount of sulphides were synthesized safely by a temperature
gradient method using metals and sublimed sulfur as the raw materials,
and a sulphur concentration cell was developed by using
MgS+1.5%ZrS2 as solid electrolyte and Mo+MoS2 as reference electrode. The sulphur content in carbon--saturated liquid
iron (oxygen activity degreea[O] ≤2×10 -6) at
1623 K was determined by using the prepared sulphur concentration cell.
The gas leakage and splitting crack were solved by optimizing the
structure of solid electrolyte tubes, hydration and oxidation of
the sulphide were also avoided by using special processes. The
results showed that the sulphur concentration cell could be
continuously used with stable signals and good reproducibility.
