Nucleation Controlled in the Aggregative Growth of Strontium Carbonate Microcrystals

The influence of PABA(p-aminobenzoicacid) and HEEDTA (N-(2-hydroxyethyl) ethylenediamine- N, N, N- triacetic acid) on Strontionite crystals via simple CO2 diffusion route is described. The results showed that the experimental parameters have great influence on the shape evolution of products. The presence of templating species and varied pH are the key primary conditions for the growth morphology. Spike like crystals self assembled in the form of flower like and cauliflower shaped cluster with high crystallinity were identified. The crystals undergo an interesting morphology changes and have been characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) techniques.
