Estudio y optimización de los parámetros de reacción para la obtención de material geopolimérico

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2004
The alkali activation of some bulk clays at room pressure and temperature leads to high strength cementitious materials called geopolymers. These inorganic polymers consist of 3D polysialate framework..

Sonochemical Synthesis of Zeolite A from Metakaolinite in NaOH Solution

open access: yesMATERIALS TRANSACTIONS, 2010
Sonochemical synthesis of zeolite A has been conducted by ultrasonic irradiation of mixtures of metakaolinite and NaOH solution. The hydrothermal synthesis at conventional synthesis conditions was undertaken to determine the sonochemical reliability. The enhancement of nucleation and crystallization rate of zeolite A was achieved by ultrasound.

Hydrothermal Preparation of Solidified Materials form Metakaolinite, Quartz and Slaked Lime

open access: yesJournal of the Ceramic Society of Japan, 2007
Solidified materials were prepared by hydrothermal treatment of metakaolinite derived from the thermal dehydroxylation of kaolinite. Hydrothermal solidification was performed under saturated steam pressure at 180°C using powder-compacts consisting of metakaolinite, quartz and slaked lime.
