| description | The formation phenomena of silver carbonate (Ag<sub>2</sub>CO<sub>3</sub>)–silver iodide (AgI) solid solutions were investigated by X-ray diffraction, thermogravimetry-differential thermal analysis, and electrical conductivity measurement. Results revealed that AgI and Ag<sub>2</sub>CO<sub>3</sub> reacted with each other when mixed at room temperature. The reaction products were classified into three types: (1) AgI-based solid solutions in the AgI-rich region for <i>x</i> = 10% or less in <i>x</i> Ag<sub>2</sub>CO<sub>3</sub>–(1 − <i>x</i>) AgI; (2) Ag<sub>2</sub>CO<sub>3</sub>-based solid solutions in the Ag<sub>2</sub>CO<sub>3</sub>-rich region for <i>x</i> = 60% or more; and (3) silver carbonate iodides in the intermediate range for <i>x</i> between 10% and 60%. For the AgI-based solid solutions, the incorporation of Ag<sub>2</sub>CO<sub>3</sub> into the AgI lattice expanded the unit cell and enhanced electrical conductivity. The solubility limit of Ag<sub>2</sub>CO<sub>3</sub> into the AgI lattice estimated from the differential thermal analysis was <i>x</i> ≈ 5%. |
