纳米级金红石相二氧化钛晶胞数原子数和晶面原子数的计算与研究

The calculation of crystal cell, atomicity and crystal plane atomicity of nano-rutile titania

以矿物晶体结构、晶体化学理论为基础,通过对纳米级金红石相二氧化钛颗粒的晶胞数、原子数及平行(001)面的表面原子数的计算,讨论了它们与纳米级金红石二氧化钛颗粒尺度大小的相关规德,并结合纳米微粒的特性对其进行了简要分析。

Based on crystal structure and crystal chemistry theory, this paper puts forward the minimum dimension of the nano-rutile titania corpuscle. Through calculating the crystal cell number, atomicity and external atomicity on the （001）crystal plane of rutile titania grains of different granularities, the paper also describe their characteristics, and analyzes their relationship with specificities of the nano-rutile titania corpuscle.
