We have grown chemical gardens in different sodium silicate solutions from several metal-ion salts--calcium chloride, manganese chloride, cobalt chloride, and nickel sulfate--with cations from period 4 of the periodic table. We have studied their formation process using photography, examined the morphologies produced using scanning electron microscopy (SEM), and analyzed chemical compositions using X-ray powder diffraction (XRD) and energy dispersive X-ray analysis (EDX) to understand better the physical and chemical processes involved in the chemical-garden reaction. We have identified different growth regimes in these salts that are dependent on the concentration of silicate solution and the nature of the cations involved.
我们已经在几种金属离子盐（氯化钙、氯化锰、氯化钴和硫酸镍）的不同硅酸钠溶液中培养出了化学花园，这些盐的阳离子来自元素周期表的第 4 周期。我们使用摄影术研究了它们的形成过程，使用扫描电子显微镜（SEM）检查了所产生的形态，并使用 X 射线粉末衍射（XRD）和能量色散 X 射线分析（EDX）分析了化学成分，以更好地理解化学花园反应中涉及的物理和化学过程。我们已经确定了这些盐中的不同生长阶段，它们取决于硅酸盐溶液的浓度和所涉及的阳离子的性质。
