摘　　要：实验涵盖"多晶原料合成→物相分析→单晶生长→材料结构性能表征"一套系统完整的晶体材料制备及表征流程,目的在于培养应化专业学生的综合实验能力。通过观察晶体生长过程理解结晶动力学因素(如过饱和度、温度、物质扩散)对晶体结晶习性及形貌的影响;学会几种重要的材料表征方法;巩固晶体结构基础知识;最终引导学生综合运用知识的同时,掌握科学系统的研究方法。A systematic and integrated experiment including "polycrystalline powder synthesis→phase analysis →crystal growth→material characterization" was established to improve the students’ comprehensive and analytical ability. The basic knowledge of crystallography was involved during practical crystal growth process. On one hand, the effect of crystal growth dynamics factors(such as supersaturation, temperature and material diffusion) on crystal growth habits and morphology can be interpreted more deeply. On the other hand, the students can learn some important methods of material characterization. Moreover, the basic theory of crystal structure can be mastered. Importantly, the capability of applying theoretical knowledge to practice was improved and a research approach with systematic science principle can be learned through this experiment at last.
