A standard material containing chrysotile asbestos for the validation of x-ray diffractometric quantitation was developed using an asbestos-containing building material i.e., perlite board. The board as the base material was crushed, pulverized, and homogenized. The homogeneity of the powder of perlite board was estimated by analysis of variance. The diffraction intensity values of the crystall...
The XDD beamline (http://ssls.nus.edu.sg/facility/beamlines/xdd/xdd.htm) at SSLS delivers a tunable monochromatized photon source with high resolution in a wide energy range (2.3-10 keV). This hard x-ray light source is ideal for diffractometry, fluorescence detection and absorption spectroscopy, especially the study of XAFS (x-ray absorption fine structure) and XANES ( X-ray Absorption Near Ed...
X-ray powder diffractometry/Rietveld refinement was employed to estimate the purity of several chrysotile powders for calibrating standards. α-Corundum powder was mixed into each chrysotile sample as an internal standard. X-ray diffractometry was performed on these mixtures, and the mass fractions of amorphous and impurity phase content were calculated using Rietveld refinement. The chrysotile ...
