The research consists of three parts: First is to prepare the five high-purity synthetic evaporite minerals powders, including gypsum, calcite, chalcanthite, nitratine and hydromagnesite, and to verify their phases and purities by XRD. Second is to conduct a series of thermal decomposition experiments of the powders by TGA at various heating rates and isothermal condition.
