Abstract
The X-ray diffraction analysis of some soil identified in Rivers State of Nigeria, Sodium Aluminum Silicate and Potassium Aluminum Silicate ( and ) were studied using the Debye-Scherrer method and a diffractometer. The lattice constants were evaluated using radiation of wavelength, = 1.5418 A and the results obtained were 13.730 0.006A and 13.500 0.006A for and respectively. The sizes of the unit cell were examined in terms of textural parameters such as particle size and number of atoms per unit cell. The values of the lattice constants suggest their Bravis lattice, the metal to metal distances, the metal to non-metal distances and the distance of closest approach of the atom centres. The metal to metal and non-metal to non-metal distances were obtained as respectively for Sodium Aluminum Silicate; while it’s metal to non-metal distance was obtained as A. Also metal to metal and non-metal to non-metal distances were obtained as respectively for Potassium Aluminum Silicate; and it’s metal to non-metal distance was obtained as A.

Structural transformations induced in graphite by grinding: Analysis of 002 X-ray diffraction line profiles

TL;DR: In this paper, the x-ray diffraction line profiles of the 002 reflections of graphite samples ground in a ball mill for periods up to 90 hours were studied using newly developed peak analysis methods that permitted separation of overlapping peaks having different peak positions, intensities, and line-breadths.

A crystallinity index for soil kaolins and its relation to parent rock, climate and soil maturity

TL;DR: In this article, a new empirical index of crystallinity was obtained from the X-ray diffraction patterns of eight standard kaolins, which can be tentatively related to the presence of weatherable minerals in the soil and/or the length of the dry season.
