Inhibition of Sintering by Si During the Conversion of Si-Rich Ferrihydrite to Hematite
BET Ferrihydrite Si Sintering XPS
2011/12/2
Abstract: The distribution and chemical state of Si in a synthetic 2-line ferrihydrite with a Si/(Si + Fe) molar ratio of 0.11 was studied. Heat treatment under oxidizing conditions shows that Si-rich...
Sintering of Montomorillonites Pillared by Hydroxy-Aluminum Species
Calcination Hydroxy-Al Infrared spectroscopy Montmorillonite Mossbauer spectroscopy Pillared interlayer complex Thermal stability
2012/1/9
The sintering of montmorillonites pillared by hydroxy-Al species was investigated by several techniques. The change of the microporosity of the pillared interlayer clay with temperature shows that sin...
