XRDThe structure-building phenomena within clay aggregates are governed by forces acting between clay particles. The nature of such forces is important to understand in order to manipulate the aggregate structure for applications such as settling and dewatering. A parallel particle orientation is ...
The lattice expansion with DMSO (or hydrazine hydrate), if necessary after grinding with CsCl, is used for the XRD of kaolinites and for distinguishing them from chlorites that show the (002) reflection at 0.71 nm. Dehydrated halloysite and kaolinite are distinguished by the rate of reaction ...
矿体多呈不规则之块体,长、宽自数公尺至十余公尺,有的有分带现象,内带(靠近硫气孔或蚀变中心)常出现蛋白石质白土,中带是明矾石化,外带是高岭石化,最外围是蒙脱石化黏土,但这种分带在各处未必都存在。这类高岭石结晶度较差,属无序高岭石(或称耐火土型),XRD峰度较宽,在2θ19～22o之间各峰分解度欠佳,其X...
XRD:X-ray powder diffraction data were collected in a standard laboratory diffractometer Rigaku-Dairix with CuKα radiation and Bragg–Brentano geometry. The diffractometer was set in step-scan mode with steps of 0.01° and with a counting time of 5 s. The powder samples were prepared by back...

XRD and 29 Si and 27 Al MAS-NMR were used to determine when a specific mineral was completely transferred into the gel phase. Electron diffraction using transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HREM) were employed to establish the amorphous nature ...
Dickite and nacrite were originally distinguished from kaolinite on the basis of XRD data, however this is seldom easy, especially in the presence of feldspar and quartz. Infra-red and differential thermal analysis can be successfully used to make the distinction between these two clays. View ...
