Aluminum incorporation into magnesium silicate hydrate (M-S-H) [PDF]
Cement and Concrete Research, 2020 Abstract The incorporation of aluminum in magnesium silicate hydrate (M-S-H) phases was investigated. Magnesium (alumino) silicate hydrate (M-(A-)S-H) with Mg/Si ratios equal to 1.1 or 1.7 and Al/Si ranging from 0 to 0.2 were synthetized in batch experiments and equilibrated at 20, 50 and 70 °C. pH values between 9 and 10.5 were observed and aluminum

Cyclic growth of hierarchical structures in the aluminum-silicate system [PDF]
Journal of Systems Chemistry, 2015 Abstract Background Biological structures grow spontaneously from a seed, using materials supplied by the environment. These structures are hierarchical, with the ‘building blocks’ on each level constructed from those on the lower level.

Silicate Removal in Aluminum Hydroxide Co-Precipitation Process [PDF]
Materials, 2014 The removal mechanisms of silicate using an aluminum hydroxide co-precipitation process was investigated and compared with an adsorption process, in order to establish an effective and validated method for silicate removal from wastewater. Adsorption isotherms, XRD and FT-IR analyses showed that silicate uptake occurred by adsorption to boehmite for ...
