Na2SiO3, commonly known as sodium metasilicate, is a versatile inorganic compound with the chemical formula Na₂SiO₃. It appears as a white, granular powder or colorless liquid, depending on its hydration state—most commonly as the pentahydrate (Na₂SiO₃·5H₂O) or anhydrous form. This compound is produced through the reaction of sodium hydroxide (NaOH) with silicon dioxide (SiO₂) under high-temperature conditions, typically in a furnace at 1,000–1,400°C, followed by leaching and crystallization processes.
In industrial applications, Na2SiO3 serves as a powerful alkali and buffering agent. Its pH typically ranges from 12.2 to 12.7 in a 1% solution, making it ideal for heavy-duty cleaning. The silicate ions (SiO₃²⁻) form protective films on metal surfaces, preventing corrosion, while sodium ions enhance detergency by emulsifying oils and suspending dirt. According to the U.S. Geological Survey (USGS) 2025 Mineral Commodity Summaries, global sodium silicate production exceeds 1.2 million metric tons annually, with North America consuming over 200,000 tons, primarily in detergents (45%), pulp and paper (20%), and water treatment (15%).
Structurally, Na2SiO3 consists of polymeric silicate anions where silicon atoms are tetrahedrally coordinated by oxygen, linked in chains or sheets. This polymeric nature imparts unique properties like high alkalinity, sequestration of divalent cations (e.g., Ca²⁺, Mg²⁺), and gelation in acidic environments. In detergent formulations, it replaces phosphates, complying with U.S. EPA Clean Water Act regulations that limit phosphorus to under 0.5% in laundry products since 2010. A 2024 study by the American Cleaning Institute highlights that metasilicate-based cleaners achieve 25-35% better grease removal than non-silicate alternatives.
Historically, sodium metasilicate was first commercialized in the early 20th century by PQ Corporation (now Ecoya), revolutionizing soapless detergents. Today, in 2026, with rising sustainability demands, Na2SiO3 anhydrous grades are favored for low-water formulations in eco-friendly products. Its solubility exceeds 30g/100ml at 20°C, and it remains stable up to 800°C before decomposing into sodium silicate glass.
For USA buyers, regulatory compliance is key: Na2SiO3 meets TSCA (Toxic Substances Control Act) listings, with no Proposition 65 warnings. FDA approves it indirectly in food-contact cleaners under 21 CFR 178.1010 as a corrosion inhibitor. In water treatment, it adheres to NSF/ANSI 60 standards for drinking water additives at doses below 20 mg/L. Bulk densities range from 0.7-1.0 g/cm³ for powders, enabling efficient packaging.
Shijiazhuang Standard IMP&EXP CO.,LTD., with over 20 years in chemical manufacturing, produces Na2SiO3 using high-purity quartz sand and caustic soda in our state-of-the-art fermentation and crystallization facilities. Our two dedicated departments ensure consistent quality: one for anhydrous Na2SiO3 via spray drying, another for hydrated forms via controlled hydration. Exported to USA, Brazil, Australia, and more, our product undergoes rigorous testing per ASTM D4400 for alkalinity and ISO 9001 protocols.
Key variants include:
- Technical Grade Na2SiO3: 99% SiO₂ + Na₂O content, for detergents.
- Soluble Grade: Low viscosity for liquid cleaners.
- Anhydrous Na2SiO3: For high-concentration mixes.
Environmentally, Na2SiO3 biodegrades rapidly in wastewater, with silicate precipitating as inert silica. Unlike aggressive caustics, it offers safer handling (LD50 >2,000 mg/kg oral). In adhesives, it acts as a deflocculant; in welding fluxes, it stabilizes arcs. Our OEM/ODM services customize ratios (e.g., SiO₂:Na₂O = 1:1 to 3.3:1), matching your formulations.
