Abstract : Investigation has been made to study the crystallization patterns in Belousov-Zhabotinsky (BZ) type oscillatory
reaction. This was consisting of acetyl acetone (AA), succinic acid (SA), Ce +3 /Fe +2 ions, and acidic bromate (BrO 3 ˉ ) which
refers to dual organic substrates, metal catalysts and initiator respectively. In the solution-phase, concentric rings like wave
patterns were observed for a period of 6-45 min. A colloidal state which comprises of numbers of fine particles was observed
after 150 min. After 30 min. These particles start to organize spontaneously in forms of solid-state nucleation centers. With
the function of time, the nucleation centers grown up into some symmetric and spherical crystal patterns named as
spherulites. The fine solid particles was involved in the formation of complex structure are regarded as primary building unit
of crystal patterns. The primary crystal units were involved into self-assembly followed by crystallization which forms
spherilutic crystal patterns of symmetric structures.
Keywords - Chemical oscillation, Crystallization, Growth kinetics, Self-organization, Organic substrate, Morphology,
Spherulites.
