摘    要:采用共沉淀法合成了Mg-Al-Cr、Co-Mg-Al三元类水滑石和两个替换二价和三价同时部分替换的Co-Mg-Al-Cr的四元类水滑石样品.应用X-射线衍射、差热分析和比表面积测定等分析方法对样品进行研究及表征.研究结果表明,合成了晶型比较完好的水滑石化合物,合成三元类水滑石比四元类水滑石较容易,且其晶型比合成的四元类水滑石更为理想.

关 键 词:水滑石化合物  共沉淀法  合成  表征

Abstract:In this paper ,the samples of Mg-Al-Cr ,Co-Mg-Al ,and Co-Mg-Al-Cr hydrotalcite-like compounds (HTLcs ) were prepared by using coprecipitation method . And the samples were studied by X-ray diffraction (XRD ) ,differential scanning colourimetry (DSC ) ,and Brunner-Emmett-Teller method (BET ) .The result showed that all the precursors formed the structure of HTLcs .
Keywords:hydrotalcite-like compounds  coprecipitation method  synthesize  characterization
