Most carbonates tend to decompose on heating to give the metal oxide and carbon dioxde. The relative rates of the formation of the diffusion channels in the surface product layer and the increase in the internal partial pressure determine whether the internal reaction advances at a steady rate or arrests until thermal decomposition of Ag2O of the surface product layer occurs at higher temperatures. atmosphere: kinetic simulation of overlapping mass-loss and mass-gain processes in a solid–gas system.
