Abstract
Thermal analysis of phase transformations of finely divided silver nitrate was carried out using scanning differential microcalorimetry. The division was obtained by penetration of silver nitrate into the cavities of mesoporous materials. The pore radii lie between 7.3 and 65 nm. This study points out the decrease of the liquid ⇄ solid transition point with the pore radius for rising and falling temperatures while the polymorphic transition temperatures, still greatly decreased for cooling, are increased for heating. Nucleation theory allows to connect these transition temperature differences of finely divided material to the size of critical nuclei taking into account the elastic energy due to specific volume variations.
