Monodispersed fine particles of calcium oxalate: morphological dynamics with tuning of the experimental parameters

Abstract

The new period of science and technology implies control over the size and shape of materials. In determining the properties and potential application of materials the morphology variation plays an important role. The present study focuses on the fabrication of calcium oxalate (CaC₂O₄) in a nano range having uniform and novel particle morphology. The powder materials having monodispersed particles of plate-like and donut-shaped morphologies were successfully synthesized by a controlled precipitation method under extensively optimized experimental parameters. The morphology of the as-prepared uniform fine particle systems was studied by scanning electron microscope and the mechanical functional surface groups and crystallinity of the test material were examined by Fourier transform infrared spectroscopy (FT-IR) and (XRD) X-ray diffraction analysis, respectively. The effect of different parameters on calcium oxalate particle morphology was also investigated. The observed results explored a significant effect of technological parameters on particle size, shape, and uniformity. Therefore, monodispersed unique particle systems of calcium oxalate were synthesized under a narrow set of experimental conditions through a reproducible recipe protocol.
