Abstract Layered double hydroxides with the chemical composition [M2+6Al3(OH)18][(SO4)2Na(H2O)6)].6H2O (M2+ = Zn, Mn, Mg) were synthesized by co-precipitation with increasing pH and ripened at 90 °C. X-ray diffraction patterns confirmed the high crystallinity and expected basal distances of the samples. Microscopic techniques (SEM and TEM), confirmed the platelet-like morphology with submicrometric dimensions along the platelets and nanometric dimensions in the basal directions, also confirmed by the Scherrer equation. Additionally, the hydrodynamic diameter of particles was analyzed by dynamic light scattering, zeta potential, dissolution and buffering studies were conducted in acid media. The submicrometric particle sizes increased in the order Mg/Al LDH

摘要 化学成分为 [M2+6Al3(OH)18][(SO4)2Na(H2O)6)].6H2O (M2+ = Zn, Mn, Mg) 的层状双氢氧化物是通过共沉淀法合成的在 90°C。X 射线衍射图证实了样品的高结晶度和预期的基础距离。显微技术（SEM 和 TEM）证实了血小板样形态，沿血小板具有亚微米尺寸，在基底方向具有纳米尺寸，也由 Scherrer 方程证实。此外，通过动态光散射分析颗粒的流体动力学直径，在酸性介质中进行 zeta 电位、溶解和缓冲研究。亚微米粒径按 Mg/Al LDH 的顺序增加
