Sodium Silicate – Alkaline
Sodium silicate is a generic name for chemical compounds with the formula Na2xSiyO2y+x or (Na2O)x·(SiO2)y, such as sodium metasilicate (Na2SiO3), sodium orthosilicate (Na4SiO4), and sodium pyrosilicate (Na6Si2O7). The anions are often polymeric. These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts.
Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass. The product has a wide variety of uses, including the formulation of cements, coatings, passive fire protection, textile and lumber processing, manufacture of refractory ceramics, as adhesives, and in the production of silica gel. The commercial product, available in water solution or in solid form, is often greenish or blue owing to the presence of iron-containing impurities.
In industry, the various grades of sodium silicate are characterized by their SiO2:Na2O weight ratio (which can be converted to molar ratio by multiplication with 1.032). The ratio can vary between 1:2 and 3.75:1.[1] Grades with ratio below 2.85:1 are termed alkaline. Those with a higher SiO2:Na2O ratio are described as neutral.

Sodium silicate, also known as water glass or liquid glass, is used in various industrial applications due to its properties as an alkaline, adhesive, and protective agent. Here are the primary industries that utilize sodium silicate (alkaline):
- Construction Industry
- Concrete and Mortar Additive: Sodium silicate is used in concrete and mortar as a setting and hardening agent. It improves the strength, durability, and resistance to water and chemicals of the concrete.
- Sealants and Adhesives: It is used in sealants and adhesives for construction applications, where it helps in bonding materials such as glass, metal, and concrete.
- Textile Industry
- Dye Fixation: Sodium silicate is used in the textile industry for dye fixation. It helps in setting dyes on fabrics and improving color fastness.
- Fabric Sizing: It is used as a sizing agent to improve the texture and finish of textiles.
- Paper and Pulp Industry
- Paper Manufacturing: Sodium silicate is used in paper production as a binding agent and to improve the strength and durability of the paper.
- Deinking: It is also used in the recycling process to help remove ink from recycled paper.
- Water Treatment Industry
- Water Softening: Sodium silicate is used in water treatment plants as a water softener. It helps to prevent scaling and corrosion in water systems by forming a protective layer on metal surfaces.
- Clarification: It is used in water clarification processes to aid in the removal of suspended solids.
- Chemical Industry
- Catalyst and Reactant: Sodium silicate is used as a catalyst and reactant in various chemical processes. It is involved in the production of silica gels and other silicon-based chemicals.
- pH Adjustment: It is used to adjust pH levels in various chemical formulations and processes.
- Detergent and Cleaning Products Industry
- Cleaning Agents: Sodium silicate is used in detergents and cleaning products as a builder. It enhances the effectiveness of surfactants by softening water and preventing the precipitation of calcium and magnesium salts.
- Industrial Cleaners: It is used in industrial cleaning solutions to remove grease, oil, and other contaminants from surfaces and equipment.
- Ceramics and Glass Industry
- Ceramic Glazes: Sodium silicate is used in ceramic glazes to improve the appearance and durability of ceramic products.
- Glass Manufacturing: It is used in the production of glass to modify the properties of the glass, including its hardness and chemical resistance.
- Agriculture Industry
- Soil Stabilizer: Sodium silicate is used as a soil stabilizer in agriculture to improve soil structure and reduce erosion.
- Pesticide Additive: It is used as an additive in pesticides to enhance their effectiveness and adherence to plant surfaces.
- Mining Industry
- Flotation Agent: Sodium silicate is used in the mining industry as a flotation agent. It helps in separating valuable minerals from ores during the flotation process.
- Fireproofing Industry
- Fireproof Coatings: Sodium silicate is used in fireproof coatings and treatments for materials. It enhances the fire resistance of materials by forming a protective layer that inhibits the spread of flames.
- Agricultural Chemicals
- Fertilizer Additive: Sodium silicate can be used in the formulation of certain fertilizers to enhance their effectiveness and provide additional nutrients to plants.
- Oil and Gas Industry
- Drilling Fluids: Sodium silicate is used in drilling fluids for oil and gas extraction. It helps to control the viscosity and stability of the drilling fluid.
Sodium silicate’s alkaline properties, combined with its ability to act as a binder, water softener, and pH adjuster, make it valuable across these diverse industrial applications.
