ZnS纳米陶瓷微球的制备
Effect of High Gravity Field on Synthesis of ZnS Polycrystalline Microspheres
摘要
Abstract
High densified ZnS polycrystalline microspheres have been successfully synthesized by the hydrothermal method with high gravity field using ZnCl2 and Na2 S2 O3 as precursors in the aqueous solution–chlorobenzene system. The effect of precursor concentration, temperature and the relative centrifugal field on the property of ZnS microspheres is investigated. The products are characterized by field-emission scanning electron microscopy (FE-SEM), Transmission electron microscopy (TEM), powder X-ray diffraction ( XRD) , UV-Vis, IR spectra and BET. It is found that the as-prepared products are the spherical ZnS particles with the diameter of 300-500nm, which is self-assembled by the crystallites with the size of 2-20nm. The density of the microsphere is relevant with the relative centrifugal field. The smaller the size of ZnS crystallites is, the bigger the density of the formed ZnS particles is. High densified ZnS polycrystalline microspheres have been successfully synthesized by the hydrothermal method with gravity field of 1000/g at 120 ℃ for 30 min in the aqueous solution–chlorobenzene system.关键词
