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.
