包覆硼氢化锂的表面结构表征及稳定性研究
Study on Surface Structural Characterization and Stability of Coated Lithium Borohydride
摘要
Abstract
To restrain the hygroscopicity of lithium borohydride and improve its stability during storage and application, olefin and polyester carbonate were used to coat on the surface of lithium borohydride by solvent evaporation method.The surface structure of coated lithium borohydride was studied by X-photoelectron energy spectra,diffuse reflection infrared spectra,roman spectra and scanning electron microscope,and its stability in the air was examined.The results show that the uniform coating layer is formed on the surface of coated lithium borohydride and the covered degree reaches to 82%.The defective surface can be effectively covered by the reaction product after exposed in the air for one hour to hinder the further reaction and make the relative stability degree increase by 50.7%.关键词
