Sodium Silicate Market

The sodium silicate market is expected to grow from USD 6.0 billion in 2026 to USD 7.4 billion by 2031, at a CAGR of 4.4% during the forecast period.

The sodium silicate market is experiencing stable demand, as the material is widely used in washing agents and cleaning products, paper processing, construction, water treatment, bonding agents, and chemical production. Sodium silicate lets manufacturers adjust the silica-to-sodium oxide ratio to achieve the properties required for specific applications. In detergents, it helps stabilize pH and meet cleaning demands for both household and industrial use. Sodium silicate is also used in the paper industry as a hydrogen peroxide stabilizer and in the de-inking process, while its binding and sealing properties can be used in construction and civil engineering. Sodium silicate is also used as a raw material for silica-containing products, including silica gel, precipitated silica, and zeolites, ensuring strong demand in downstream chemical industries. Producers offer a wide variety of sodium silicate products in liquid and solid forms, depending on the processing and handling methods customers choose.

PQ Corporation (US) is a global supplier of various silicates and silicas. PQ was established in Philadelphia, where the first sodium silicate was produced in 1861. PQ specializes in sodium silicate production and offers it in various forms, including solid glass, hydrated silicate powders, and ready-to-use liquid sodium silicate. Sodium silicate produced by PQ is used in cleaning, construction, chemicals, and paint manufacturing applications. In the cleaning industry, the company offers sodium silicate for household and industrial detergents used to provide cleaning efficiency. In construction, sodium silicate is used in geopolymers, building materials, and other applications. The company currently has more than 31 production sites and over 1,500 employees worldwide.

Qemetica (Poland) is an industrial chemical company specializing in silicates and developing sodium and potassium silicates in solid and liquid form. Qemetica operates production plants in Iłowa and Żary in Poland, where sodium silicates are manufactured for different industries. The company's sodium silicate portfolio includes glass silicate and sodium silicate solution. Qemetica can also develop special product solutions to meet customer needs. The company claims that all silicates produced use high-quality raw materials and modern production facilities. In 2021, Qemetica put a new furnace into operation, increasing production capacity by 30%. The company is reportedly the largest supplier of sodium silicate in Europe.

Evonik Industries AG (Germany) is a leading specialty chemicals company with a dominant market position in silica and silicate technologies. The company's Smart Effects product line manufactures and processes silicates and silica products. Sodium silicate is a key raw material for its silica-based products. Sodium silicate (or waterglass) is also used as a raw material for precipitated silica such as SIPERNAT, ULTRASIL, SPHERILEX, ZEODENT, and ZEOFREE. Evonik's silicate and silica unit serves industries including pulp & paper, rubber, construction, food, animal nutrition, home care, adhesives, and plastics. The company's Wesseling, Germany, site is a major hub for silica and silicate production and research. Evonik's silicate industry unit relies on a production network for precipitated silica and sodium silicate in Europe, Asia Pacific, and the Americas. The company emphasizes manufacturing tailored products for optimal application.

Nippon Chemical Industrial Co., Ltd. (Japan) has operated since 1893 as a manufacturer of inorganic chemicals, including phosphorus compounds, silicates, barium salts, chromium compounds, electronic materials, and specialty chemicals. The company's product line includes sodium silicate, comprising liquid sodium silicate, sodium silicate glass, and several silicate variants. Its liquid sodium silicate range includes various grades with different silica-to-sodium oxide ratios to meet different industrial needs. The company also uses its sodium silicate products in building and tunnel foundations. It has long-standing experience and expertise in silicate production and distribution dating back to the 1980s. Nippon Chemical Industrial has branches in the US, China, Thailand, and Taiwan. As of March 2026, it reported having 691 employees and total net sales of approximately JPY 39.8 billion. Its international presence is significant, as it is involved in all phases of the sodium silicate supply chain and supplies the product to numerous applications.

Occidental Chemical Corporation (OxyChem) (US), formerly a wholly-owned subsidiary of Occidental Petroleum Corporation (US), is one of the leading producers and distributors of sodium silicates in the United States. The corporation supplied its customers with sodium silicate in different liquid forms based on various ratios of silica to sodium oxide, as well as in granular form of anhydrous and pentahydrate sodium metasilicates. Sodium silicates were used by various industries, such as the soaps & detergents industry, pulp & paper industry, water treatment, catalysts, paints & pigments, and construction materials. The corporation had sodium silicate manufacturing plants in Chicago, Dallas, Cincinnati, Mobile, and Augusta. According to Occidental Petroleum's 2024 annual report, OxyChem had an annual production capacity of 0.6 million tons of sodium silicate. However, on January 2, 2026, Occidental finished the deal to sell OxyChem to Berkshire Hathaway for USD 9.7 billion.
