Analysis and Implications of the Edge Structure of Dioctahedral Phyllosilicates
Celadonite Edge structure Illite Muscovite Octahedral site Phengite
2012/1/9
Crystal growth theory was applied to describe edge sites of phyllosilicates. Three face configurations were found to exist. One face has one tetrahedral site per tetrahedral sheet and two octahedral o...
Dehydroxylation of Dioctahedral Phyllosilicates
Dehydroxylation Iron Montmorillonite Mossbauer spectroscopy Oxidation Smectite
2012/2/9
Mossbauer spectroscopy of dioctahedral phyllosilicates showed that on dehydroxylation iron which originally occupied M(2) and M(1) sites became, respectively, 5- and 6-coordinated. The 6-coordinated s...
