为了了解硅酸铝在初始水热过程和高纯斜沸石合成过程中的生长行为,利用小角X射线散射(SAXS)和X射线衍射(XRD)图、扫描电镜(SEM)图像、紫外拉曼(UV - Raman)和傅里叶变换红外(FT - IR)光谱分析了硅酸铝纳米颗粒的物理化学特征。结果表明:在初始反应时间为120 h之前,硅酸铝纳米颗粒的表面分形(Ds)值先减小后增大;之后,随着反应时间的延长(120 ~ 144 h),从质量分形(Dm)向质量分形(Dm)转变,但在144 h后Dm值开始下降。因此,提出了它们从均匀分散到聚集甚至聚集的生长机制。
In order to understand the growth behaviors of the aluminosilicate species in the initial hydrothermal process and thereafter synthesis of clinoptilolites with high purity, the physicochemical characteristics of the aluminosilicate nanoparticles were elucidated by small angle X‐ray scattering (SAXS) and X‐ray diffraction (XRD) patterns, scanning electron microscopy (SEM) images, Ultra‐Violet Raman (UV‐Raman) and Fourier transform infrared (FT‐IR) spectra. The results demonstrated that the aluminosilicate nanoparticles presented the first decreased surface fractal (Ds) values and then an increasedDsvalues in the initial reaction time of before 120 h. After that, the fractal transformations fromDsto mass fractal (Dm) occurred with the extensions of reaction time (120–144 h), but the decreasedDmvalues appeared after 144 h. Therefore, their growth mechanisms from uniform dispersions to aggregation, and even assembly were proposed.
