The effect of mechanical and thermal treatment on the characteristics of saponite-containing material

Записки Горного института
Solving the problems of modern building materials science is reduced to obtaining high-quality materials, expanding and searching for a rational raw material base, which can be carried out through the use of various industrial wastes.

Elucidating the crystal-chemistry of Jbel Rhassoul stevensite (Morocco) by advanced analytical techniques [PDF]

, 2008
The composition of Rhassoul clay is controversial regarding the nature of the puremineral clay fraction which is claimed to be stevensite rather than saponite.

Evaluation of saponite and saponite/sepiolite fluids for geothermal drilling [PDF]

, 1991
The rheology and other properties of drilling fluids containing saponite and a saponite-sepiolite mixture as the main vicosifier have been systematically evaluated in the temperature range of 300-600{degree}F under appropriate confining pressures up to ...

Potential of Cu–saponite catalysts for soot combustion [PDF]

, 2016
H– and Na–saponite supports have been prepared by several synthesis approaches. 5% Cu/saponite catalysts have been prepared and tested for soot combustion in a NOx + O2 + N2 gas flow and with soot and catalyst mixed in loose contact mode.

Synthesis and characterisation of boron and gallium substituted saponite clays below 100 degrees Celsius and 1 atmosphere [PDF]

, 2005
This paper describes a simple procedure for the synthesis of saponites with isomorphous substitution of Si4+ by B3+ and Ga3+ below 100°C and at 1 atmosphere. The XRD patterns of the Ga- and B-substituted saponites are similar to Al-substituted saponites.

The Role of Chlorate‐Driven Oxidative Weathering in Shaping Clay Deposits on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Oxidized clays and the widespread Al/Si‐over‐Fe/Mg stratigraphy on Mars imply prolonged water‐rock interactions and efficient oxidative weathering despite the largely anoxic conditions of Early Mars when most deposits formed during the climate optimum.

Interaction of Eu-isotopes with saponite as a component of the engineered barrier [PDF]

, 2013
Bentonite is accepted as the best clay material in the engineered barrier of deep geological repositories (DGRs) for radioactive waste disposal. In recent years, the interactions between a wide range of rare-earth (REE) cations and smectites have been ...

Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks.
