Effect of EDTA on the Morphology and Size of SrCO₃ Particles during Crystallization

Abstract:

Strontium carbonate particles with different morphologies and sizes were synthesized successfully by a precipitation method in the presence of ethylenediaminetetra-acetic acid disodium (abbreviate as EDTA) at 25 . The phase structure and morphology of these SrCO3 particles were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The XRD results showed that orthorhombic crystalline SrCO3 particles were prepared in the absence of and presence of EDTA. It was found that this additive played an important role in controlling the morphology and size of the particles, which changed from dendritic to spherical shape as EDTA was added.
