Sintering behaviour of sepiolite

Ceramics International, 1997
Abstract Sepiolite containing minerals from various regions of Turkey were processed to investigate their sintering behaviour over a wide temperature range. The sintering was studied by mercury porosimetry and nitrogen adsorption (BET). Microstructural features were investigated using SEM and TEM techniques.

Poly(vinyl alcohol) nanocomposites with sepiolite and heat‐treated sepiolites

Journal of Applied Polymer Science, 2009
AbstractPoly(vinyl alcohol) (PVA) nanocomposites with pristine sepiolite and heat‐treated (HT) sepiolites were prepared by the method of solution dispersion. The measurements of XRD, FTIR, TEM, and AFM were used for the characterization of the nanocomposites.
