Sodium silicate is produced by reacting silica with sodium carbonate (soda ash)
between 1200°C and 1400°C. It is a colorless compound of oxides of sodium and
silica. Sodium silicate is a generic name for a range of compounds derived from
soluble silicate glasses that are water solutions of silicon dioxide and sodium oxide
in various ratios. These compounds are commercially sold as 20% to 50% aqueous
solution. Aqueous solution of sodium silicate is called water glass. Sodium silicate is
stable in neutral and alkaline solutions. In acidic solutions, silicate ion reacts with
hydrogen ions to form silica acid. Silica acid when heated and roasted forms silica
gel—a hard, glassy substance.

Sodium silicate has numerous applications in various industries. Key applications
include detergents, water treatment, paper & pulp, and building & construction
materials. Sodium silicate is an excellent adhesive for sealing fireboard boxes. It is
extensively used in drilling fluids to stabilize borehole wells. In addition, building
materials such as concrete, stucco, and plasters when treated with sodium silicate
solution helps reduce their porosity to a large extent, making them durable and
water repellent. Sodium silicate is utilized as a fixative in the dyeing and coatings
market. It is used as a binder in refractories and investment casting and as a
polishing agent in silicon wafers. It has several other niche applications such as
passive fire protection, food preservation, automotive & metal repair, and
aquaculture.
Rising demand for detergents and cleaning agents is expected to augment demand
for sodium silicate in the near future. Additionally, increasing demand for sodium
silicate in the construction & building materials industry coupled with rising number
of water treatment projects is likely to drive demand for sodium silicate during the
forecast period. However, competition from substitute products such as soda ash
could restrain growth of the sodium silicate market. Growing need for enhanced oil
recovery (EOR) due to energy conservation policies, high fuel prices, and
technological development could open up new avenues for growth of the sodium
silicate market in the near future.
