Thermodynamic analysis and experimental research of the chlorination of nickel ferrite (NiFe2O4) by gaseous chlorine in the presence of added C, BaS, S and NaCl in the temperature range from 300 to 900¾C are given in this paper. Nickel ferrite chlorination in the presence of BaS and CaCl2 was carried out in the temperature range from 750 to 950¾C. The presence of added C, BaS, S and NaCl intensifies the chlorination process of nickel ferrite by gaseous chlorine and reduces the temperature the reaction begins at from 700 to 300¾C. It is concluded that the process of nickel chlorination without …

The paper presents a thermodynamic analysis and experimental research on the kinetics of the chlorination of nickel silicate (2NiOÀSiO2) by gaseous chlorine and calcium chloride without additives and in the presence of added C, BaS, S and NaCl, to intensify the process. The influence of temperature in the range from 673 up to 1223 K for various chlorination times has been studied. Additives increases the chlorination rate. The kinetics of the process were determined by the analysis of dependence of the nickel chlorination rate on time and temperature. It was established that nickel chlorination without additives is a chemically-controlled reaction, …
