Abstract
The sulphur capacity of CaO-SiO2-Al2O3-MgO-FetO slags with fixed slag composition,at different temperature and under different gas pressure was measured using gas-slag equilibrium techniques.In Pt crucible,the slag was equilibrated with a mixture of CO,CO2,SO2 and N2 at required partial pressures of oxygen and sulphur.It was shown that,the sulphur capacity of slag decreases with the increase of temperature under constant gas pressure;at a constant temperature the rising of oxygen pressure results in an increase in sulphur capacity.
