Understanding the Hydration Process of Salts: The Relation between Surface Mobility and Metastability

In this work, the relation between mobility and metastability is investigated. This done under pure water vapor vacuum conditions. First, properties of metastable zone conditions are investigated compared to those atmospheric Second, using electrochemical impedance spectroscopy, whereby we differentiate bulk surface mobility. Using mobility, showed that a prerequisite for nucleation K2CO3. Sufficient must be introduced diffusion ions water, an increase almost two orders magnitude (800 times) observed on hydrated sample. It has been shown both consequence energy barrier low ion at pressures.
