Synthesis of zeolite through hydrothermal process has been commonly used for decades.
However, it does not satisfy the serious terms of sustainability that leads to reduction of …

Zeolites, known as molecular sieves, are crystalline hydrated aluminosilicates of alkali earth
cations. They have a three-dimensional structure that contains frameworks of [SiO 4] 4-and …

The properties of metakaolin-based geopolymer are directly impacted not only by the
specific surface and composition of initial metakaolin and the type, composition and relative …

Isothermal conduction calorimetry (ICC) is used here to measure the kinetics of
geopolymerisation of metakaolin by reaction with NaOH solution under a variety of …

Geopolymers are a class of aluminosilicate materials synthesized by alkaline or alkali-
silicate activation of solid alumina-and silica-containing precursor materials at ambient or …

The aim of this work is to determine the most convenient calcination temperature of kaolinite
clays in view of producing geopolymer cements. In this light, the clay fractions of three kaolin …

A three key parameters (SiO2/Al2O3, M2O/Al2O3 and H2O/M2O, M denotes Na or K)
composition design method was firstly proposed based on chemical characteristics analysis …

The effect of heat treatment parameters on the dehydroxylation/amorphization process of the
kaolinite-based materials such as natural and artificial kaolin clays with different amounts of …

Four metakaolins were prepared by calcination of a natural Spanish kaolin (Navalacruz
deposit, Zamora province) at 600, 700, 800, and 900° C. These four metakaolins, more …

The synthesis of zeolite materials by hydrothermal transformation of natural Jordanian kaolin
in NaOH solutions of various concentrations was investigated at 100° C for 20 h. A mixture of …
