Effective boundary area of decomposition and dissolution of agglomerated lead carbonate

Determination of Effective Surface Area for the Chemical Reaction of Fine Particulate Materials

“…The value Qd was plotted against the compressive stress, I? As shown in Figure 6, recited from [13], Q, increased rapidly with compressive stress showing the superiority of the fine agglomerates over coarse ones for dissolution reaction. The change in (2, with compressive stress is explained by assuming the change in the effective surface area during the reaction.…”

“…The agglomerated particles were subsequently sieved into two fractions, a coarse one with average diameter, d,, = 505 pm, and a fine one, d,, = 115 pm. The cumulative pore size distribution curve was always bimodal, indicating the coexistence of the intra-and inter-aggregate pores [13].…”
