This review presents contemporary perspectives on the nature, synthesis methods, and application areas of sodium aluminosilicates as one of the most in-demand classes of silicate materials. Geochemical mechanisms of the formation of sodium-containing aluminosilicates in magmatic, metamorphic, and sedimentary systems are considered, including pressure-induced structural transformations of amorphous phases, features of crystallization of minerals of the nepheline group, and the role of alkali elements in the evolution of the silicate network. Experimental and technological approaches to the synthesis of sodium aluminosilicates are summarized, ranging from geopolymerization and alkaline activation of technogenic wastes to thermal treatment of ashes, slags, and biomass. Special attention is paid to the mechanism of formation of sodium-aluminosilicate hydrate (N-A-S-H) gels, the influence of activator composition, phase transformations, and the possibilities for controlling the structure and properties of the resulting materials. The review demonstrates a wide range of applications of sodium aluminosilicate systems, including construction and composite materials, sorption and catalytic processes, protective and functional coatings, water treatment, soil stabilization, and the utilization of technogenic wastes. Prospects for the development of energy-efficient technologies for producing sodium aluminosilicates from alternative raw materials are outlined, along with approaches to enhancing the durability, structural stability, and functionality of these materials for industrial and environmental applications.
