The study of chlorination kinetics of copper(I)sulfide by calcium chloride in the presence of oxygen

The article investigates the influence of temperature, time, quantity of calcium chloride, and oxygen flow on the chlorination degree of copper(I)sulfide by calcium chloride in the presence of oxygen. Scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) analysis were used to determine morphological changes occurring with the change of temperature and time. The law of additive time and the method of stationary point were used to determine kinetic parameters, i.e., rate constant and activation energy.
