Experiments were carried out at 1175–1350°C to study the phosphate capacity of CaO‐CaCl 2 slags and the sulphide capacity was calculated according to the correlation between the two capacities. At 1200°C the logarithm of the phosphate capacity increased from 24.5 to 26.5 with increasing CaO mole fraction from 0 to 0.22 in the slags and it decreased with increasing temperature. Sulphide capacity increased both with increasing CaO mole fraction and temperature. A good linear correlation was found between slag carbonate capacity and phosphate capacity as well as sulphide capacity. Optical basicity was used to evaluate the property of the CaO‐CaCl 2 slag in the present study. The value of optical basicity of CaCl 2 is established as 0.63. The correlations of optical basicity with above mentioned three capacities were found to be linear.
