Preparation of montmorillonite modified phenolic resin for shell process [PDF]

open access: yesChina Foundry, 2009
The development of montmorillonite modified phenolic resin under microwave irradiation heating was investigated. The effect of montmorillonite content and stirring time on the structure and morphology of synthetic resin was analyzed.

A Test for Montmorillonite

open access: yesNature, 1952
IT has been shown that montmorillonite saturated with small ions, for example, lithium, is difficult to rehydrate after being dried at moderate temperatures1–3. This behaviour has been found to be confined to montmorillonite and forms the basis of a new test which enables the mineral to be easily distinguished from the other common montmorillonoids4.

Fourier transform infrared spectroscopy analysis for hydrothermal transformation of microcrystalline cellulose on montmorillonite

open access: yes, 2014
Specifying the interactions between montmorillonite and cellulose is helpful for understanding the evolution of biomass in soil and the geological formation of fossil fuels in nature.

Intercalation of metformin into montmorillonite

open access: yesDalton Transactions, 2018
Metformin hydrochloride is spontaneously intercalated into layered silicates like montmorillonite by an ion-exchange mechanism, producing a promising controlled release system.

Effect of lead on the sorption of phenol onto montmorillonites and organo-montmorillonites [PDF]

open access: yesJournal of Colloid and Interface Science, 2007
The effect of lead (Pb) on the sorption of phenol onto montmorillonite-based sorbents was studied using a batch equilibration method when phenol and Pb were sorbed simultaneously and either Pb or phenol was previously sorbed. The sorbents were Na(+)-, Ca(2+)-, hexadecyl trimethylammonium (HDTMA)-Na(+)-, and HDTMA-Ca(2+)-montmorillonites.

The morphology of the Unter-Rupsroth montmorillonite

open access: yes, 1957
Electron micrographs of Na-saturated Unter-Rupsroth montmorillonite show that many of the individual flakes, which are probably 10 Å. thick, have straight edges meeting in 120° angles.

Effects of humidity and interlayer cations on the frictional strength of montmorillonite

open access: yesEarth, Planets and Space, 2018
We developed a humidity control system in a biaxial friction testing machine to investigate the effect of relative humidity and interlayer cations on the frictional strength of montmorillonite.
