摘要
从晶体化学和晶体结构的角度,根据堇青石的晶胞参数、晶胞内原子排列的特点等,提出了堇青石最小颗粒的假设,从理论上得出了堇青石最佳的纳米尺度。同时通过对堇青石颗粒的晶胞数、原子数、表面晶胞数以及平行(010)面的表面原子数的计算,列出了堇青石纳米结构参数的表征,讨论了它们与纳米级堇青石颗粒尺度大小的相关规律,并结合纳米微粒的特征对其进行了简要的分析。
On a basis of crystal structure and crystal chemistry theory, according to the crystal cell parameters of cordiefite and the atomic arrangement in its crystal cell, etc., the article gave the minimum dimension of nano - cordierite corpuscle. Through calculation of the crystal cell number, atomicity, external crystal cell number and the external atomicity on the（010）crystal plane of different granularities, their characteristic were given, and the relationships between them and the speeifieities of nano - cordierite corpuscle were analyzed.
