Vietnam is cutting silica sand exports due to diminishing reserves and government restrictions, alarming buyers in Southeast Asia. VRX Silica reports robust offtake demand from customers seeking reliable alternatives, but its Arrowsmith North mine is still months from construction. Near-term supply shortage is expected to push prices upward.
Asia
Asian sodium silicate prices weakened in January and February before recovering in March, particularly in China. The rebound was supported by firmer soda ash and silica-linked input costs, along with improved chemical activity. China’s industrial value added rose 6.1% year-on-year in Q1’26, while manufacturing increased 6.4%, supporting demand from detergents, adhesives, paper, water treatment, and precipitated silica. However, construction demand stayed weak, as real estate development investment fell 11.2% and newly started floor space declined 20.3%, limiting stronger demand from construction chemicals and concrete treatment. Soda ash export movement also helped ease domestic supply pressure and supported upstream sentiment.
Europe
European sodium silicate prices were stable-to-firm in Q1’26 due to higher energy and processing costs. Euro area industrial producer prices rose 3.4% month-on-month in March, while energy prices increased 11.1%, raising costs for silica fusion, steam, drying, packaging, and transportation. Demand remained limited because construction activity weakened, with euro area construction output down 1.2% year-on-year and building construction down 7.1%. Detergents, water treatment, paper, and precipitated silica applications provided baseline demand, but buyers avoided heavy restocking.
North America
North American sodium silicate prices showed a firmer tone in Q1’26, supported by higher inorganic chemical costs and steady industrial demand. The U.S. PPI for other basic inorganic chemical manufacturing rose from 162.501 in January to 164.280 in March, while industrial chemical costs also strengthened. Construction spending reached USD 2,185.5 billion in March, up 1.6% year-on-year, supporting demand for concrete treatment, adhesives, sealants, water treatment, and industrial binders.
Analyst Insight
According to Procurement Resource, in the near term, sodium silicate prices may remain stable-to-firm if energy, freight, and soda ash costs stay elevated. Stronger construction and detergent demand would support further gains.

Asia
In the Asian market, the prices of sodium silicate were relatively stable to slightly weak during the fourth quarter of 2025. This was because the demand from the key industries of detergents, construction chemicals, and paper remained moderate. The prices of raw materials were relatively stable, with silica prices remaining comfortable due to smooth mining activities. At the same time, the prices of caustic soda remained stable across the Asian markets. In China, the demand for sodium silicate remained cautious, with many consumers preferring to consume the existing stocks instead of ordering new ones. In India, the market performed relatively better, driven by the stability of the industrial output. However, the demand from the Asian market remained relatively low, not sufficient enough to increase the prices.
Europe
In the European market, the prices of sodium silicate moved within a narrow range in the fourth quarter. The demand for the product in the construction, coating, and special chemical sectors was stable, but the demand growth was not robust. Buyers were selective in their purchases in view of the uncertain economic scenario, and the focus was entirely on the short-term market. The supply side was well covered, driven by stable silica supply and energy costs at manageable levels. Although the demand for high-grade silicates in the special chemical sector was providing support, it was not impacting the overall price trend in any significant manner.
North America
In North America, sodium silicate prices were relatively stable in Q4’25, with some slight downward pressure in certain regions. The natural slowdown in construction and related end-user markets dampened buying interest towards the end of the quarter. However, sodium silicate manufacturers operated at stable production rates, and raw material availability was secure, so there was no concern of any shortages. Demand from the detergents and industrial cleaning agents’ markets was steady, although buying behaviour was subdued.
Analyst Insight
According to Procurement Resource, Sodium Silicate prices are likely to be stable to slightly lower, depending on the rate of recovery in construction and industrial markets.

Sodium silicate is produced by mixing silicon dioxide (SiO2) and sodium oxide (Na2O). This water-soluble, colorless compound has stabilizing, binding, and adhesive qualities. Numerous industrial applications of sodium silicate include employment as a cement additive, a flame retardant in textiles, a component of detergents, and a binder in building materials. When combined with acids, it can produce a solid gel, making it useful in a variety of industrial applications.

The reaction between silica sand and caustic soda in a superheated steam flow reactor leads to the production of sodium silicate via pulverization and heating.
Silica sand and soda ash reaction at around 851°C with applied pressure through steam gives sodium silicate.
