Abstract

is clarified, which promotes ion diffusion and interfacial redox reactions. This work offers critical theoretical guidance for optimizing process parameters, enabling the low-energy, high-efficiency production of CaO with minimal CaS byproducts and advancing the sustainable utilization of industrial gypsum.
