Table 4 presents the particle size distribution of MK and BFA. The BFA shows a broader particle size distribution when compared with MK. BFA mean particle size is 39.07 μm, significantly higher than that of MK (5.71 μm). Accordingly, the values of the specific surface area (BET) are 3.05 m 2 /g and 16.30 m 2 /g, respectively.
