摘要
报道了三元体系硝酸镧 -甘脲 -水 (La(NO3) 3-Glycoluril-H2 O)在 30℃时等温溶度与饱和溶液的折光率 ,绘制了相应的溶度图及饱和溶液折光率指数曲线。体系中形成新相 La(NO3) 3· 2 Glycoluril· 2 H2 O,为异成份溶解化合物。通过元素分析、红外光谱分析以及 X-射线粉末衍射分析对新相进行了表征。
Ternary system La(NO 3) 3 Glycoluril H 2O, as a potential complex slow release fertilizer, was investigated by isothermal method at 30℃. Its phase diagram and refraction indices were constructed. A new incogruent phase, La(NO 3) 3·2Glycoluril·2H 2O, was formed, This new compound was studied by elementary analysis, IR and X ray diffraction.
