Abstract

A study on the low temperature synthesis of layer silicates was undertaken on the systems SiO2/Mg2+, SiO2/Al3+ and SiO2/MgO/LiF. Initial work was carried out on the uptake of silica from dilute solutions of magnesium at room temperature and atmospheric pressure to ascertain the amount of silica adsorbed in precipitates formed under these conditions. Reflux of these solutions gave products analogous to the serpentine minerals, chrysotile and antigorite. Electron microscopy was used to study these products. Electron diffraction provided a means of identifying some of the phases and morphological features observed were discussed in terms of silicate structures. Similar studies were made on the SiO2/Al3+ system at room temperature and atmospheric pressure and under reflux conditions. The products of these reactions were mainly hydroxides of aluminium. Attempts were made to chelate mildly the aluminium in solution to hinder the precipitation of hydroxides and encourage silicate synthesis. A series of organic and inorganic additives were used and the solutions heated at 80
