(Na2SiO3)
Sodium silicate, commonly known as water glass, is an important inorganic compound widely used in chemical, industrial, and commercial applications. It is produced in various purity grades, ranging from industrial-grade (≥30% SiO₂) to high-purity or laboratory-grade (≥40% SiO₂), suitable for diverse manufacturing processes. The silicate ratio (SiO₂:Na₂O) is an important specification, typically ranging between 2:1 to 3.5:1 depending on the intended application. These grades are carefully manufactured to ensure consistent chemical performance and compliance with international quality standards.
Sodium silicate is supplied in liquid and solid forms. Liquid solutions are viscous, clear to slightly cloudy, and colorless to light amber, while solid forms include powder or granules, which are water-soluble. The material maintains its chemical stability when handled properly and is designed for efficient transport and storage. Analytical parameters, including SiO₂ content, Na₂O content, pH, and viscosity, are strictly monitored to guarantee consistent quality.
Production of sodium silicate adheres to ISO, ASTM, and other international standards, ensuring chemical composition, purity, and performance consistency. Each batch undergoes quality control tests for silica content, alkalinity, and impurity levels. Certificates of Analysis (COA) are provided to confirm compliance, supporting industrial, chemical, and laboratory applications.
Sodium silicate has a broad range of applications across industries:

Sodium silicate is available in 25–50 kg bags, 500–1000 kg jumbo bags, drums, and bulk liquid containers. Packaging is designed to protect the product from moisture, maintain quality, and facilitate safe handling and transportation for both industrial and commercial clients.
Sodium silicate is alkaline and can cause skin and eye irritation upon direct contact. Proper personal protective equipment (PPE) such as gloves, goggles, and protective clothing is recommended. In case of spills, the material should be contained and neutralized properly. While generally considered safe for the environment when diluted, concentrated solutions should not be released into natural water systems to prevent ecological impact.
Sodium silicate should be stored in cool, dry, and well-ventilated areas, away from moisture, acids, and incompatible chemicals. Liquid solutions should be kept in corrosion-resistant tanks, while solid forms should be sealed in moisture-proof containers to prevent caking and degradation. Proper storage ensures chemical stability, product longevity, and safety for users.
Sodium silicate is a multi-functional chemical essential in construction, water treatment, detergents, paper, textiles, ceramics, and adhesives. With multiple grades, forms, and international quality compliance, it is a reliable and versatile solution for industries worldwide. Correct handling, storage, and adherence to safety protocols ensure efficient, environmentally responsible, and safe use of sodium silicate across applications.
