A reevaluation of crystal-size distributions in chromite cumulates
reevaluation crystal-size distributions chromite cumulates
2012/4/9
Although studies have shown that igneous cumulates can form byin situ crystallization without requiring crystal settling, it has not been demonstrated that crystal-size distribu-tions (CSDs) are consi...
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 ...
Influence of Al Substitution and Crystal Size on the Room-Temperature Mossbauer Spectrum of Hematite
Aluminum Hematite Iron Mossbauer spectroscopy Particle size
2011/11/25
Abstract: Mossbauer spectra of 15 hematites with Al substitutions between 0 and 10 mole % were taken at room temperature. X-ray powder diffraction indicated dimensions of these hematites in the c-dire...
