The radioisotope pollution shows two types of patterns: dry and wet deposits for nuclear power plant accidents. Two surface pollution patterns were analysed by fractal. In Fukushima nuclear power pl...
Determination of Mean Crystallite Dimensions from X-Ray Diffraction Peak Profiles: A Comparative Analysis of Synthetic Hematites
BET Hematite Iron Oxides Mean Crystallite Dimension Powder X-ray Diffraction Surface Area XRD
2011/12/8
Abstract: X-ray diffraction (XRD) profile analysis of eight synthetic hematite samples was performed to identify the best parameters for determining the apparent mean crystallite dimension (D) and, co...
Comparison of Techniques for Determining the Fractal Dimensions of Clay Minerals
Adsorption Clay Fractal NMR Small-angle x-ray scattering
2011/12/27
Small-angle X-ray scattering (SAXS), adsorption and nuclear magnetic resonance (NMR) techniques were used to determine the fractal dimensions (D) of 3 natural reference clays: 1) a kaolinite (KGa-2); ...
Dehydroxylation of Aluminous Goethite: Unit Cell Dimensions, Crystal Size and Surface Area
Al-substitution Crystal size Dehydroxylation Goethite Hematite Specific surface area Unit cell
2011/12/27
This work investigates unit cell dimensions, crystal size and specific surface area of aluminous goethite that was progressively dehydroxylated to form hematite. Goethite synthesized from the ferrous ...
Relationship among Derivative Spectroscopy, Color, Crystallite Dimensions, and Al Substitution of Synthetic Goethites and Hematites
Aluminum Color Fiber-optic Doppler anemometry Goethite Hematite Visible spectroscopy
2012/1/13
Nine hematites and 22 goethites were synthesized by a variety of methods to obtain monomineralic samples having a range of Al substitutions and particle sizes. The second derivative of absorbance and ...
The Influence of Aluminum on Iron Oxides. VIII. Unit-Cell Dimensions of Al-Substituted Goethites and Estimation of Al From Them
Aluminum Goethite Iron Unit-cell dimensions X-ray powder diffraction
2011/11/25
Abstract: The unit-cell dimensions of synthetic, Al-substituted goethites showed that the c dimension is a linear function of Al substitution in the range 0?3 mole % Al, but that the a dimension is va...
