本文研究了PABA（对氨基苯甲酸）和HEEDTA（N-（2-羟乙基）乙二胺- N，N，N-三乙酸）通过简单的CO_2扩散途径对菱锶矿晶体的影响。结果表明，实验参数对制品的形状演变有很大的影响。模板物质的存在和不同的pH是生长形态的关键主要条件。发现自组装形成的穗状晶体呈高结晶度的花状和菜花状团簇。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）等技术对晶体进行了表征。
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.
