复合添加剂体系下纳米AlOOH的“有利生长基元”分析

Analysis on"Favorable Growth Unit"of Nano-AlOOH Under the Compound Additive System

晶体的结晶形态取决于"生长基元"的形成及其运动。在添加复合添加剂的体系中,呈现出"生长基元"多元化共存的倾向。但并不是每一种"生长基元"都可以成为体系中的"晶核",只有"有利生长基元"才能在溶液中稳定地存在。由于"复合生长基元"的配位体系不同于单纯多聚体的配位体系。所以,浓度不同,温度不同,"有利生长基元"也就不同。本文从稳定能出发讨论纳米AlOOH在水热复杂环境体系下的"有利生长基元"。

Crystal morphology of crystals depends on ＂growth units＂and their movement.Adding compound additives into the system,the ＂growth unit＂appears diversity.But no every kind of ＂growth units＂can become crystal nucleus of the system,Only ＂favorable growth unit＂ can stably exist in solution.As the coordination system of the ＂compound growth units＂ is different from the simple coordination polymer system,＂favorable growth unit＂ is different under different concentrations and different temperature.In this article,＂favorable growth unit＂of nano-AlOOH in the hydrothermal system under complex environment was discussed from the aspect of stability energy.
