Aluminosilicates are interweaved network of aluminates and silicates having intermolecular and intramolecular porosity for which they find application in the area of adsorption, catalysis, pyrolysis and so on. They maintain the thrust of their existing applications and still entail new applications within the fields of chemical process and separation. The product phase and properties of the aluminosilicate vary with varying synthetic methods such as the sequence of addition of reagents which is outlined here in this study. The sequence of addition of aluminium iso propoxide and sodium silicate is divided into three parts. The phases obtained are zeolite, and crystoballite alpha in part-1. The phases of part-2 are sodalite and crystoballite beta. In part-3 the phases are mostly zeolite. (C) 2020 Elsevier Ltd. All rights reserved.
