Preparation and Magnetic Property Study of Ni-P/Palygorskite Core-Shell Linear Powder

Article Preview

Abstract:

Alygorskite is a kind of hydrated magnesium aluminium silicate clay mineral. A novel linear core-shell structured Ni-P coated micro-fiber palygorskite (MFP) was fabricated via an electroless plating process in acid bath. The composition, morphology and structure of the as-prepared products were characterized by the techniques such as powder X-ray diffra-ction (XRD), energy-dispersive X-ray spectrum (EDS), and scanning electron microscopy (SEM). The Magnetic Property of the powders was conducted from a vibrating sample magnetometer (VSM). It was observed that the MFPs surface was compactly coated with irregular Ni-P particle. The XRD patterns indicate the amorphous Ni-P microstructure of coating. Magnetic properties show that coated MFPs are ferromagnetic materials. The satura-tion magnetization (σs) and coercivity (jHc) of the powders are 13.86emu/g and 43.97 Oe respectively.
