  • Sodium silicate, also known as water glass or liquid glass, available in aqueous solution and in solid form, is a compound used in cements, passive fire protection, refractory, textile and lumber processing.
  • There are two processes for preparing water glass that are common this day. The first one is by reaction in liquid phase while the next one is by reaction in solid phase. However, alkaline and quartz sand are the same raw materials used in the two processes
  • Sodium silicates are solids where the proportion between silicon, oxygen and sodium determines what will be the resulting silicates
  • Sodium silicates are manufactured by fusing sand (SiO2) with an adjusted amount of sodium carbonate to glass. This is then pulverized and dissolved in water at high temperature and pressure to water glass.
  • Soluble sodium silicates (or waterglass) are solutions of water and soluble glasses manufactured from varied proportions of Na2CO3and SiO2.
  • Sodium silicates are especially valuable as adhesives because they can change from a liquid to a semi-solid condition upon the loss of a small amount of water.
  • Sodium silicates are used for de-inking, sizing, coating, and bleaching of recycled paper products in the pulp and paper industry. The de-inking process solubilizes and removes nonfibrous materials, such as inks, from the fiber stock.
  • Sodium silicate solutions react with solutions of many soluble salts to form complex gelatinous precipitates. For instance, aluminum salts react withsodium silicate solutions to form sodium- aluminum silicate gels which can be processed to make base-exchange materials particularly suitable for water softening.
  • Sodium Silicate is a best water proofing agent and it is also used in cement industries.
  • Sodium silicate based thermal interface pastes give higher thermal contact conductance across conductor surfaces than polymer based pastes and oils, due to their higher fluidity and the consequent greater conformability.
  • The sodium silicate solution can be used easily in detergent slurry in an effort to control the viscosity at an appropriate level for powder detergent production giving optimal density.
  • Sodium silicate is widely used as a binder for molding sand in foundries. The technology for perlite/sodium silicate composite manufacture is based largely on this foundry industry experience.
  • A variety of solid-state NMR techniques were applied in order to assign resonances in the 29Si and 23Na NMR spectra of a new crystalline silicate to crystallographically distinct silicon and sodium sites, respectively.
  • The sodium silicate market is mature as many of its end uses are mature as well. Only modest aggregate growth for sodium silicate applications is projected; 0.7 percent annually through 2004.
  • The major consumers of sodium silicate are soap industry, silica gel industry, textile industry and paper industry. Of these, the largest consumer is the soap industry. About 520 kg of sodium silicate is required per tonne of soap manufactured. The total capacity of the operating soap units in the NER is estimated to be 50 tonne per day. The demand of sodium silicate for these units is estimated at 25 tonne per day.
  • The sodium silicate market size was valued at USD 5.82 billion in 2015. The product has high demand in the petrochemical industry as cracking catalyst. The growth
    of refining activities is anticipated to raise demand for cracking catalysts, which in turn is expected to have a positive impact on the industry growth over the forecast period.
