This document applies to solid compounds that can undergo reversible chemical reactions under conditions such as specific temperature ranges, atmospheres, and pressures. Reversible chemical reactions of solid compounds include redox reactions of metal oxides, decomposition and carbonation reactions of carbonates, dehydration and hydration reactions of hydroxides, etc. The measurement object of thermochemical heat storage temperature and heat storage density is the decomposition state of solid compounds, including the reduction state of metal oxides, the decomposition state of carbonates, and the dehydration state of hydroxides. This document specifies the method for measuring the thermochemical heat storage temperature and heat storage density of powdered solid compounds using a synchronous thermal analyzer in the temperature range of 100-1500°C, as well as the instruments, materials, specimens, measurement procedures, and accuracy used. , safety matters and limitations, etc.
