Effects of Aggregation of Reactant Powder Particles on the Kinetics and Mechanism of Solid State Reaction between BaCO3 and TiO2

Effective boundary area of decomposition and dissolution of agglomerated lead carbonate

“…The role of the surface area on the solid-state reaction was extensively studied. Most of them were dedicated, however, to the solid-solid addition reactions, where the significant contact is more or less point like (Blum and Li, 1961;Nagai et al, 1976). The reaction partner of the dissolution or decomposition, on the contrary, is a continuum, so the effective boundary area for a reaction is to be discussed more thoroughly from a microscopic point of view.…”
