Structural alteration of sepiolite by dry grinding J. Cornejo; ;
All these results indicated that the structural framework of sepi:? lite is mechanieally more stable than those of other clay minerals. The alteration upon grinding seems to proceed in three steps: 1) For short grinding times #171;15 min) there are a thinning and shorte#173; ning of fibrous particles producing a slight increase of the speci#173;
The results how that he sepiolite framework is rather esistant to mechanical stress and its alteration by dry grinding occurs through three successive, overlapping processes: (i) thinning of the fibrous particles without structural alteration; (ii) distortion of the parallel units of sepiolite fibres, affecting essentially the particle surface which transforms into an amorphous protective coating; (iii) disruption of the inner

Activation of natural sepiolite by means of grinding in a planetary mill followed by wet NaOH activation was studied for the purpose of endowing the product with enhanced basicity for potential catalytic/sorptive applications. Synthesized solids were characterized with Xray powder diffraction (XRD), N2 adsorption/desorption, scanning electron microscopy (SEM), energy dispersive (EDX), atomic
In this study, Vallecas sepiolite was subjected to dry grinding in a ball mill for various periods of time. Changes induced during the comminution process were examined by Xray powder diffraction (XRD), specific surface area measurements, DTATG and 1Rspectroscopy.
Sepiolite grinding millgrinding machine. Sepiolite is a clay mineral, a complex magnesium silicate, a typical formula for which is Mg4Si6O15OH21836H2O. It
The results show that the sepiolite framework is rather resistant to mechanical stress and its alteration by dry grinding occurs through three successive, overlapping processes: (i) thinning of
