N2 - In order to check the solubility of CaS during sulfide reduction in molten CaCl 2 , the mixture of CaCl 2 and a small amount of CaS was melted in Ar at the range from 1123 K to 1223 K. The melt was sampled by quartz tube and rapidly solidified. The solidified samples showed a lamella structure with CaS particles, which results in a simple eutectic reaction between CaCl 2 and CaS. Using ICP-AES analysis, the saturation of CaS was found to be completed within 1.8 ks, and 1.77 « 0.1 mol%CaS at 1173 K was measured as the solubility limit at the initial composition of 3.0 mol%CaS. A tentative phase diagram of CaCl 2 CaS binary system was proposed based on the solubility analysis in these temperatures and eutectic structure. [doi:10.2320/matertrans.MA201803]
