摘要：
In this work, Core-shell structure palygorskite/nano-CaCO3 (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 mu m diameter. The nanocomposite particles exhibit the marked thermal stability properties than the palygorskite clay mineral.
