Figure 1

SEM micrograph of cockle shells powders before (a) and after (b) the addition of BS-12. The crystals of cockle shells powders were white, larger, rod-shaped, and separated in the absence of BS-12, whereas the crystals were smaller sized, agglomerated, and clumped together in the presence of BS-12.
