The thermal decomposition of silver carbonate Ag2CO3 was studied by DTA-TG and DSC-TG, heated and cooled cyclically in the temperature range 100–200 ° C in a carbon dioxide atmosphere (1 atm). No weight change was observed. Two endothermic peaks during the heating and two exothermic peaks during the cooling were observed. These peaks were attributed to phase transitions from the normal via the β to the α phase during the heating, and the reverse phase transitions during the cooling. The results support the mechanism proposed in our previous paper in which the thermal decomposition in a carbon dioxide atmosphere proceeds via the high temperature phase of silver carbonate.
