摘要:

实验发现制备五水硫酸铜晶体时会得到多种不同的宏观晶面体。本文根据晶体生长和晶体对称性特点推测了其基本形态和形成多种晶形的原因,并根据晶体学数据讨论了目前已知的五水、三水及一水硫酸铜的结构;提出了一种新的失水过程和结构尚未被表征的二水合硫酸铜的可能结构,以期激发学生的科研热情,并对教材已有实验进行进一步学习。

关键词: 五水硫酸铜, 三水硫酸铜, 一水硫酸铜, 宏观晶面, 晶体结构

Abstract:

The crystals of copper sulfate pentahydrate prepared from laboratories have different shapes and crystallographic planes. Based on the theory of crystal growth and the symmetry theory, this manuscript makes a rough explanation. According to crystallographic data, the microstructures of the currently known copper sulfate pentahydrate, trihydrate, and monohydrate are discussed. A new dehydration process and the microstructure of copper sulfate dihydrate are also proposed.

Key words: Copper sulfate pentahydrate, Copper sulfate trihydrate, Copper sulfate monohydrate, Crystallographic planes, Crystal structure
