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 ...
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...
