Abstract
IN studying reactions between two solid phases, it is found that the reaction velocity in systems such as MgO/Ag2SO41, MgO/Ag3PO41, MgO/Mg2P2O72 and MgO/MgSiO33 is not determined by the diffusion process through the reaction products, but by reactions at one of the phase limits. The reaction velocity is independent of the thickness of the layer of reaction product and changes with temperature according to the exponential equation
