Sodium Metasilicate Pentahydrate

Sodium Metasilicate Pentahydrate is an inorganic compound appearing as a white granular or crystalline solid, chemically represented as Na2SiO3·5H2O. It serves as a source of alkalinity and silicate ions in industrial formulations. This compound typically has an alkaline pH of about 11 to 12 when dissolved at 1% concentration in water, making it effective in applications requiring elevated pH levels. Supplied predominantly in 25 kg bags or by bulk order, Sodium Metasilicate Pentahydrate requires storage in cool, dry, and well-ventilated environments to maintain stability. It should be kept away from incompatible materials such as strong acids and moisture to prevent decomposition. Typical usage rates depend on the application, for example, detergent formulations usually incorporate it at concentrations ranging from 1% to 5% by weight. Before procurement, buyers should consider handling precautions due to its alkaline nature and ensure compatibility with existing process chemistries. The product is stable under recommended storage conditions but can degrade if exposed to excess humidity or reactive substances.

In industrial detergent formulations, maintaining optimal alkalinity is critical to effectively breaking down oils, greases, and other contaminants. Sodium Metasilicate Pentahydrate raises pH levels to accelerate cleaning performance and provides water-softening capabilities by binding metal ions, which would otherwise inhibit surfactant action. Beyond cleaning, its role in addressing scaling and hardness in water treatment processes prevents equipment fouling and reduces maintenance downtime. By supplying silicate ions, it also contributes to corrosion inhibition, extending the service life of metal components in contact with treated water. These specific functional benefits enable formulators and plant operators to maintain process efficiency and product quality.
