What Is High-Purity Sodium Silicate (CAS: 1344-09-8) and Its Industrial Value?

Sodium silicate, widely identified in commercial trade by CAS number 1344-09-8 and often referred to as water glass or soluble glass, is an essential inorganic compound composed of sodium oxide (Naâ‚‚O) and silicon dioxide (SiOâ‚‚). Depending on its physical form and industrial application, sodium silicate is manufactured as viscous aqueous liquids, solid lumps, or soluble powders. Its versatile chemistry provides binding, buffering, deflocculating, and corrosion-inhibiting properties across multiple manufacturing processes.

At Shandong Look Chemical Co., Ltd., we produce and supply high-purity sodium silicate designed specifically to meet stringent industrial specifications. Industrial buyers utilize CAS 1344-09-8 in several key manufacturing industries:

  • Detergents and Cleaning Formulations: Acts as a building agent, pH buffer, and anti-corrosion protection for washing machines and metal processing parts.

  • Construction and Civil Engineering: Functions as a concrete hardener, soil stabilizer, and rapid accelerator in shotcrete applications.

  • Paper, Pulp, and Board Packaging: Serves as a high-strength adhesive in corrugated cardboard manufacturing and a stabilizing agent in pulp bleaching.

  • Foundry and Refractory Industry: Acts as a durable binder for sand molds and acid-resistant cements.

  • Water Treatment: Utilized as a corrosion inhibitor in municipal water lines and a coagulant aid in wastewater clarification.

Understanding Molar Ratio (MR) and Technical Specifications

When purchasing sodium silicate in commercial quantities, understanding the Molar Ratio (SiOâ‚‚ : Naâ‚‚O) is critical to obtaining the exact chemical performance required for your process. The molar ratio determines solubility, viscosity, setting speed, and alkalinity.

Commercial grades generally fall into two primary ranges:

  1. Neutral / High-Modulus Sodium Silicate (Molar Ratio 3.1 – 3.4): Features lower alkalinity, higher viscosity, and faster drying times. Ideal for paper adhesives, silica gel production, catalyst manufacturing, and refractory binders.

  2. Alkaline / Low-Modulus Sodium Silicate (Molar Ratio 2.0 – 2.5): Highly soluble with strong detergent action and higher alkalinity. Widely used in heavy-duty industrial cleaners, textile processing, and soil grouting.

Key Quality Compliance and Testing Standards for Chemical Buyers

Substandard or inconsistent sodium silicate can lead to severe manufacturing failures—including batch precipitation, adhesive failure in corrugated boards, or pipeline clogging in water treatment facilities. Conducting thorough chemical compliance verification prior to issuing a purchase order is essential.

At Shandong Look Chemical, every batch of CAS 1344-09-8 undergoes strict laboratory testing before dispatch. When evaluating global suppliers, demand the following quality compliance benchmarks:

  1. Certificate of Analysis (COA) Verification: Ensure every shipment comes with a lot-specific COA verifying exact Na₂O percentage, SiO₂ percentage, Baumé degree (°Bé), density, and iron trace analysis.

  2. ISO 9001:2015 Quality Management: Confirm that the synthesis and packaging processes are certified under international quality management systems to guarantee batch-to-batch repeatability.

  3. REACH & Heavy Metal Compliance: For buyers exporting to European and North American markets, compliance with EU REACH registration and strict limits on trace heavy metals (Fe, Pb, As) is mandatory for regulatory approval.

  4. Sample Testing Protocol: A reliable wholesale supplier should offer pre-shipment sample testing (100g – 1kg) allowing your lab to verify compatibility in your actual production matrix.

Sodium Silicate Bulk Pricing Factors and Sourcing Strategies

Understanding the pricing drivers behind sodium silicate (CAS 1344-09-8) enables procurement officers to optimize purchasing schedules and negotiate stable long-term contracts. Bulk market prices are primarily governed by three factors:

  • Raw Material Costs: Soda ash (sodium carbonate) and high-purity silica sand (quartz) represent over 70% of the raw material input cost. Fluctuations in global soda ash markets directly impact lump and liquid quotes.

  • Energy Inputs in Synthesis: Melting silica sand with soda ash in high-temperature furnaces (1,300°C–1,500°C) is energy-intensive. Regional energy tariffs influence baseline production costs.

  • Freight & Physical Form: Shipping solid glass lumps is significantly more cost-effective over long oceanic distances compared to transporting liquid water glass (which contains 50–60% water weight). Many international buyers import solid lumps and dissolve them locally using pressure dissolvers.

💡 Strategic Buying Tip: If your facility possesses dissolving equipment, sourcing sodium silicate solid lumps (CAS 1344-09-8) reduces ocean freight costs per ton by up to 45%. For buyers without dissolving infrastructure, requesting high-density liquid solutions in flexitanks maximizes transport efficiency.

Packaging, Handling, and Global Logistics for Wholesale Orders

Red Flags When Sourcing Sodium Silicate from Overseas Factories

Avoiding costly procurement mistakes requires vigilant supplier evaluation. When reviewing quotes from overseas chemical trading companies or factories, watch out for these 4 red flags:

  1. Vague Molar Ratio Documentation: Suppliers offering “generic” sodium silicate without stating the exact molar ratio or Baumé scale often deliver off-spec batches that fail in industrial formulations.

  2. Unusually Low Pricing Below Market Soda Ash Costs: Quotes drastically below prevailing market rates frequently indicate recycled or contaminated by-product streams containing high iron or unreacted insoluble quartz sand.

  3. Inability to Provide COA for Specific Batches: Avoid trading intermediaries who only supply “typical parameters” sheets rather than lot-specific laboratory testing certificates.

  4. Lack of Export Packaging Compliance: Insufficient drum wall thickness or unlined jumbo bags can lead to moisture absorption, caking in solid lumps, or container leakage in transit.
