Abstract

In this work, Core-shell structure palygorskite/nanoCaCO3 (PnC) composite particles have been synthesized chemically, employing solution precipitation methods. Crystal structure, morphology and thermal stability properties are investigated by means of X-ray diffraction (XRD), transmission electronic microscopy (TEM) and Thermogravimetric (TG) analysis. The results showed that the PnC particles were almost monodispersed microsphere aspect with the size was about 1-3 μm diameter. The nanocomposite particles exhibit the marked thermal stability properties than the palygorskite clay mineral.
