摘要
介绍了PABA(对氨基苯甲酸)和HEEDTA (N-(2-羟基乙基)乙二胺- N, N, N-三乙酸)通过简单的CO2注入途径对辉脱石晶体的影响。结果表明，实验参数对产品的形状演变有较大的影响。模板种的存在和pH的变化是影响其生长形态的主要条件。鉴定出花状自组装的穗状晶体和高结晶度的花椰菜状晶体。晶体发生了有趣的形态变化，并通过x射线衍射(XRD)，扫描电子显微镜(SEM)和傅里叶变换红外光谱(FT-IR)技术进行了表征。
Nucleation Controlled in the Aggregative Growth of Strontium Carbonate Microcrystals
The in fluence of PABA(p-aminobenzoicacid) and HEEDTA (N-(2-hydro xyethyl) ethylenediamine- N, N, N- triacetic acid) on Strontionite crystals via simp le CO2 d iffusion route is described. The results showed that the experimental parameters have great influence on the shape evolution of products. The presence of templating species and varied pH are the key primary conditions for the g rowth morphology. Spike like crystals self assembled in the form of flo wer like and cauliflower shaped cluster with high crystallin ity were identified. The crystals undergo an interesting morphology changes and have been characterized by X-ray d iffraction (XRD), Scanning Electron M icroscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) techniques.
