Main technical content: This document is applicable to solid compounds that can undergo reversible chemical reactions under specific temperature ranges, atmospheric conditions, and pressures. The reversible chemical reactions of solid compounds include the oxidation-reduction reactions of metal oxides, the decomposition and carbonation reactions of carbonates, and the dehydration and hydration reactions of hydroxides. The thermochemical heat storage temperature and heat storage density measurement objects are the decomposition states of solid compounds, including the reduction states of metal oxides, the decomposition states of carbonates, and the dehydration states of hydroxides. This document specifies the method of measuring the thermochemical heat storage temperature and heat storage density of powder-state solid compounds within the temperature range of 100-1500℃ using a synchronous thermal analyzer, as well as the instruments, materials, samples, measurement steps, accuracy, safety precautions, and limitations used in the process.
