摘要
从晶体化学、晶体结构的角度,根据方解石的晶胞参数、晶体内原子排列的特点等,提出了方解石最小颗粒的假设。通过对纳米级方解石颗粒晶胞数、原子数、表面晶胞数和表面原子数的计算,讨论了它们与纳米级方解石颗粒尺寸大小的相关规律,并结合纳米微粒的特性对其进行了简要分析。
On the basis of crystal structure and crystal chemistry theory, according to the crystal cell parameters,the atomic arrangement of calcite,etc. , this paper gives the minimum dimension of nano-calcite corpuscle. Through calulation of the crystal cell number,atomicity,external crystal cell number and the external atomicity of different granularities, the paper also describes their characteristics, and analyzes their relationship with the specificities of the nano-calcite corpuscle.
