Synthetic micas are materials with interesting properties that combine high charge (high
cation exchange capacity) with swelling capacity. Among the various methods for …

Nuclear Magnetic Resonance (NMR) spectroscopy has played an important role over many
years in understanding the structure and reactivity of minerals. The advent of highresolution …

Bionanocomposites based on layered inorganic components, as clays, and polymers of
biological origin, as chitosan, have a major impact in medical and environmental fields …

In this work, organo-montmorillonite (organo-Mt) and organo-synthetic mica (organo-mica),
obtained by quaternary or primary amine cations (octadecyltrimethylammonium (ODTMA) or …

High charged swelling micas, with layer charge between 2 and 4, have been found to
readily swell with water, and complete cation exchange (CEC) can be achieved. Because of …

A general stoichiometric cation exchange mechanism does not fully explain the unique
exchange behaviors of Na-4-mica, the most highly charged swelling 2: 1 phyllosilicate …

The discovery of swelling brittle mica, Na-Mica-4, has been one of the most significant
advances in the pursuit for a material with high ion-exchange capacity. For technical …

Surface modification of natural clay minerals with reagents containing metal chelating
groups has great environmental value. The functionalization by adsorption or grafting …

A sodium brittle mica with the ideal composition [Na4] inter [Mg6] oct [Si4Al4] tetO20F4 was
synthesized via melt synthesis in a gas tight crucible. This mica is unusual inasmuch as the …

Abstract Na-4-mica, a highly charged swelling mica, has suffered from insufficient
understanding of some fundamental features such as partial layer collapse and …
