Sepiolite

Sepiolite, also known in English by the German name meerschaum, is a soft white clay mineral, often used to make tobacco pipes. A complex magnesium silicate, a typical chemical formula for which is Mg₄Si₆O₁₅(OH)₂·6H₂O, it can be present in fibrous, fine-particulate, and solid forms.Sepiolite is a nanofibrous natural silicate that can be used as a nanocarrier because it can be naturally internalized into mammalian cells, due to its nano-size dimension. Therefore, deciphering ...Cellular uptake pathways of sepiolite nanofibers and DNA ... - NatureSepiolite is a hydrous magnesium silicate [7] having the chemical formula Mg 4 Si 6 O 15 (OH) ·6H 2 O. Sepiolite can be identified in hand specimen by applying a drop of a saturated solution of methyl orange on the sample. A positive test result for sepiolite turns purple.

Treatment of environmental contamination using sepiolite: current ...

To evaluate the potential of sepiolite-based materials to resolve environmental pollution problems, a study is needed which looks at the whole life cycle of material application, including the residual value of material classified as waste from the exploitation of sepiolite deposits in the region or from its processing and purification.Most sepiolite fibres have a diameter below the resolution limit of the light microscope (Alvarez, 1984). Thus, the analysis of clays, soils and dusts for the presence of sepiolite may require the use of both X-ray diffraction and electron microscopy. The crystallinity of sepiolite samples may vary considerably, but the strongest line at 1.21 nmSepiolite was considered by previous Working Groups in June 1986 (IARC ...Sepiolite 269 is used also to obtain hydrocarbons from methanol as a support to A1 and Mg - (Kitayama and Wada, 1 9 8 1 ) . , Other applications are: in the hydrogenization of gasolines obtained by cracking, containing,unsaturatedor aromatic hydrocarbons where sepiolite is a carrier for Ni (Carrpthersm Lawrence, 19651, for the hydrogenation of ...Sepiolite: Properties and Uses - ScienceDirectاحصل على السعر

Preparation and Characterization of Polypropylene/Sepiolite ...

Polypropylene (PP)/sepiolite nanocomposites were prepared using the melt blending technique. The effects of nano-sepiolite content on the mechanical property, thermal property, crystallinity, morphology and rheological property of PP/sepiolite nanocomposites were investigated.To allow the use of fibrous-like clays, as sepiolite, in different applications, their disaggregation and the formation of stable suspensions are crucial steps to enhance their performance significantly, e.g., in cellulose nanofibrils/clay composite formulations, enabling an adequate mixture of the matrix and filler individual components.
