  • Dehydration–rehydration in magnesium vermiculite ...

    The dehydrationrehydration of Mgvermiculite, as large flakes (7 × 5 × mm) and powder (⩽ 80 µm), has been studied. Samples were treated in a sealed bomb at 140 and 100 °C for several days. After dehydration, they were rehydrated at room temperature. The samples were examined by …

    Feb 26, 2018· Hence, this interstratification should be denoted as R2 illite–dioctahedral vermiculite. However, an R2 illite–smectite Rietveld structural model fitted the measured XRD pattern of the R2 illite–dioctahedral vermiculite in different states very well and can be used for quantification purposes in natural or artificial mixtures.

  • INTERSTRATIFICATION VERMICULITE by The Clay Minerals …

    micas from vermiculite may proceed through an interstratification of the two in a manner analogous to weathering of biotite to vermiculite through an interstratified stage. Onedimensional Fourier synthesis from the intensities of the 001 diffraction maxima of the interstratified mixture was carried out.

  • Inorganic modification of Palabora vermiculite UPSpace

    vermiculite did not show a relatively better thermal expansion ratio, despite the presence of both ammonia and water in the interlayer. In the increasing ionic potential series: Navermiculite, Bavermiculite, Cavermiculite and Mgvermiculite, it was found that the onset expansion temperature also increased dramatically.
