摘要
晶体是具有高度周期性排列结构的固体,是一种物质结构确定的存在形式。其明确的结构特性使得晶体在诸如激光、超导、催化等科技前沿领域扮演着重要角色。然而,本科教学中晶体结构对比实验环节的不足,限制了学生对晶体结构深入的理解。针对这一问题,本文设计了基于沉淀法和水热法的晶体生长实验,旨在通过合成具有不同晶相的钒酸铋(BiVO_(4)),对比分析其粉末X射线衍射花样和形貌的不同,深化学生对晶体结构的认识,同时提升他们的综合实验技能和专业素养。
Crystals are solids with highly periodic structural arrangements and represent a definite form of substance structure.Their distinct structural characteristics enable crystals to play a significant role in cutting-edge technological fields such as lasers,superconductivity and catalysis.However,the deficiency of comparative crystal structure experiments in undergraduate teaching limits students′in-depth understanding of crystal structures.To address this issue,crystal growth experiments based on precipitation and hydrothermal methods were designed,aiming to synthesize bismuth vanadate(BiVO_(4))with different crystal phases and compare the differences in powder X-ray diffraction pattern and morphology.This approach deepened students′understanding of crystal structures while enhancing their comprehensive experimental skills and professional literacy.
