Thermal Behavior of a Natural Sepiolite from Northeastern Iran

Thermal Behavior of a Natural Sepiolite from Northeastern Iran 131 were removed, but crystal structure of sepiolite was maintained (Fig. 1). Heatng the samples up to 550°C, totally eliminated the peak at 12.06 nm, indicating the total degradation of sepiolite dihydrite. The slight increase in the peaks at ~1.018 and ~0.813 nm (Fig. 1)

Sepiolite | IMA Europe

Sepiolite-based rheological additives provide viscous fluids with thixotropic behaviour when they are dispersed in water or other liquid systems. Sepiolite suspensions are stable even in systems with high salt content (high ionic strength) unlike suspensions of other clays, such as bentonite.

1-5-2015 · For PLA/sepiolite nanocomposites, their crystal structure and crystallization behavior have been investigated in detail by FTIR in this article. The IR spectra in the wavenumber range from 890 to 1000 [cm.sup.-1] of PLA/S1.0 nanocomposite with isothermally crystallized at different temperatures for 1 h are illustrated in Fig. 10.

Sepiolite Mineral Data

Post J E , Bish D L , Heaney P J , American Mineralogist , 92 (2007) p.91-97, Synchrotron powder X-ray diffraction study of the structure and dehydration, behavior of sepiolite, Sample: T = 742 K, Locality: Durango, Mexico

Synchrotron Powder X-ray Diffraction Study of the ...

Real-time, temperature-resolved synchrotron powder X-ray diffraction data and Rietveld refinements were used to investigate the behavior of the sepiolite structure from 300 to 925 K. Rietveld refinements revealed that most of the zeolitic water is lost by ~390 K, accompanied by a decrease in the a and c unit-cell parameters.

Morphological, Thermal, and Mechanical Behavior …

The effect of the preparation approach and the amount of nanoclay were evaluated to check their influence on thermal, morphological, and mechanical behavior of the final nanocomposites. Regardless of the preparation approach, all nanocomposites showed improvements in thermo‐mechanical properties with increasing contents of sepiolite.
