Influence of OH- concentration on the illitization of kaolinite at high pressure
(Elsevier, 2011)
The products of hydrothermal reactions of kaolinite at 300°C and 1000 bars were studied in KOH solutions covering an OH- concentration, [OH-], of 1M to 3.5M. XRD patterns indicated a notable influence of the [OH-] on the ...

A new route of synthesis of Na-Mica-4 from sodalite
(Elsevier, 2014)
Synthesis of Na-Mica-4 has been achieved by a ``mix and calcine¿¿ method using sodalite and magnesium fluoride as the only precursors. Previous research found sodalite as a key intermediate reaction product in the formation ...

Synthesis temperature effect on Na-Mica-4 crystallinity and heteroatom distribution
(Elsevier, 2015)
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 applications, the control of the phase evolution ...

Exploring the benefits of depositing hard TiN thin films by non-reactive magnetron sputtering
(Elsevier, 2013)
The aim of this paper is to compare the mechanical and tribological properties of TiN coatings prepared in a conventional magnetron sputtering chamber according to two different routes: the usual reactive sputtering of a ...
