Ca-Rectorite from Sano Mine, Nagano Prefecture, Japan
2:1 Layer Silicate Margarite Rectorite Regular Interstratification Smectite/Brittle Mica
2011/12/22
Abstract: Rectorites containing various amounts of Ca were found at the Sano Mine, Nagano Prefecture, Japan. The Ca content in nonexchangeable form varied from 1.0 to 3.9% CaO. With more than 3.4%, th...
Further Investigations on the Rehydration Characteristics of Rectorite
Electrostatic effects Hexagonal holes Interlayer cation Rectorite Rehydration mechanism Thermal dehydration
2011/12/31
The rehydration and rehydroxylation properties of homoionic rectorites (saturated with Ca2+, Mg2+, Na+, or K+) were further investigated. The rehydration properties of the rectorite were characterized...
