摘要
本文用X-射线衍射、透射电子显微镜、选区电子衍射研究了LiCl/γ-Al_2O_3、KCl/γ-Al_2O_3、CsCl/γ-Al_2O_3诸体系,结果表明,加热KCl与γ-Al_2O_3或者CsCl与γ-Al_2O_3的混合物,KCl、CsCl能在γ-Al_2O_3表面呈单层分散,它们的最大单层分散量分别为0.051gKCl/100m^2γ-Al_2O_3,0.082gCsCl/100m^2γ-Al_2O_3,而加热LiCl和γ-Al_2O_3混合物时,LiCl则和γ-Al_2O_3反应生成体相化合物Li_2O·5Al_2O_3。
Systems of LiCl/γ-Al2O3, KCl/γ-Al2O3 and CsCl/γ-Al2O3 are investigated by using X-ray diffraction, transmission electron microscopy and electron diffraction. The results show that heating the mixtures of KC1 and γ-Al203 or CsCl and γ-Al203, KC1 and CsCl can disperse onto the surface of y-Al2O3 to form a monolayer with a dispersion capacity of 0.051g KCl/100m2γ-Al2O3 and 0.082g CsCl/100m2γ-Al2O3 respectively. While heating the mixture of LiCl and γ-Al2O3, LiCl reacts with y-AlO3 to form a balk compound Li2Oγ5Al2O3.
