What Is Sodium Silicate?

Sodium silicate, commonly known as “waterglass”, is prominent due to wide commercial and industrial application. It is often composed of an oxygen-silicon polymer backbone housing water in molecular matrix pores. Sodium silicate products are manufactured as solids or thick liquids, depending on intended use. For instance, waterglass functions as a sealant in metal components. Lastly, although sodium silicate production is a mature industry, there is ongoing research for new applications given its heat conductive properties.

Molecular composition

Sodium silicate is a silicon-oxygen polymer containing ionic sodium (Na+) components. Such a molecular arrangement is different from typical ionic materials such as salt, which is based on formula units united by electrical attraction. By contrast, sodium silicate is similar to carbon-based plastics since silicon-oxygen-silicon bonds between each monomer are covalent. The polymer-like nature of the sodium silicate matrix as well as the polar character of oxygen and sodium atoms allows for bonding of water molecules within the polymer matrix. Therefore, sodium silicate products often exist in hydrous allotropes. (Wells, “Structural Inorganic Chemistry”).

Physical properties

Physical properties of sodium silicate-based substances make them very attractive for commercial/industrial use. Liquids and solids based on sodium silicate and produced by PQ Corporation have a density from 1.6g/cubic cm. to about 1.4 g/cubic cm. Also note that the data tables contain information on the observed state of each product under moderate conditions. Sodium silicate products exist as white solid and a variety of liquids with visibly different properties. Differences in reaction conditions and manufacturing methods lead to clear, opaque, and “syrupy” waterglass products. (PQ, “Sodium Silicates. Products and Specifications”)
