[交流] 做水滑石的请进！求助急！完全不懂合成的现象为什么是这样啊！

本人不是做催化剂的，只是稍微涉及到了一点水滑石的合成，第一次做，完全搞不懂什么情况，请了解水滑石的虫友帮帮忙！
参考的文献主要是附件中的文献，但是感觉不大靠谱啊！
我看其他文献还有大家讨论的水滑石的合成一般会用到混碱--氢氧化钠和碳酸钠，还涉到缓慢滴加，严格控制pH之类的很复杂的操作，为什么这篇的方法只是硝酸镁、硝酸铝混合盐溶液快速倾倒至氢氧化钠碱液中？而且合成的形貌也非常规整？我重复了这个操作，搅拌混合溶液（水热之前）感觉是胶体一样，不怎么会沉下去，难道水滑石在水中分散性不错么？还是我做的根本没有生成水滑石？
我想利用水滑石很漂亮的六边形，请懂的虫友帮忙如何控制条件！大家觉得附件中的文献可靠么？还是有什么关键步骤被省略了？求解！谢谢！
