摘要
通过简易的热力学模型推测晶体宏观形状及缺陷的成因,借助于本科无机探究实验,培养明矾大晶体并测量其宏观参数,拟合出明矾的热力学参数,以解释明矾的宏观形状、缺陷并预测明矾的完美八面体的可能性与晶体的自范性。
In this paper, a simple thermodynamic model of crystal macroscopic morphology and the cause of the defects were suggested. By virtue of growing alum(K) crystals and measuring their macroscopic parameters in the inorganic laboratory for undergraduates, we can calculate the thermodynamic parameters of alum, thus explaining the macroscopic morphology and defect of alum(K), and predicting the possibility for alum(K) to generate octahedral crystals and its self-normality.
