摘　　要：文章介绍了晶体形状的形成机理并综述了复杂结构无机晶体的可控合成方法。晶体形状是由其生长习惯和分形生长确定的,液相合成利用实验条件调整晶体本身的生长习惯,被证明是复杂结构无机晶体最广泛使用也是最成功的合成方法之一;电沉积法由于可以随意地设计晶体的生长条件和生长环境,同时可以随时停止和随时重新开始结晶,为探讨复杂微结构的结构形成机理提供了一种通用且简单的实验途径;自相似生长为晶体生长提供了新的思路,使得尺寸、取向和形貌可控的较大的等级结构的合成成为可能。The formation mechanism of the basic crystal shape and the controllable synthesis of inorganic crystals with complex shape are introduced. A basic crystal shape is determined by habit formation and branching growth. The crystal habit can be tuned by experimental condition when inorganic crystals are synthesized in solution, which is proved to be one of the most widely used and most successful synthesis methods for inorganic crystal with complex structure. Electrodeposition provides a common and simple way to study the formation of complex structure since it can casually design the growth condition and the growth history and have the unique capability to pause and resume crystallization at any stage. Self-similar growth leads to new reflections on crystal growth, which enables the synthesis of large hierarchical structures with controlled size, orientation, and morphology.
