Sodium Metasilicate Pentahydrate
Wyoming Chemical Distribution supplies high-quality Sodium Metasilicate Pentahydrate for a wide range of industrial and commercial applications. This versatile alkaline compound is widely used in detergents, metal cleaning, ceramics, water treatment, and industrial cleaning formulations due to its excellent cleaning performance, water-softening capabilities, and corrosion-inhibiting properties.
When dissolved in water, Sodium Metasilicate Pentahydrate forms a highly alkaline solution that helps remove oils, grease, dirt, and other contaminants while improving cleaning efficiency. Its strong buffering action, dispersing properties, and ability to inhibit corrosion make it a preferred ingredient in numerous cleaning and processing applications.
Sodium Metasilicate Pentahydrate contains silica (SiO₂) and sodium oxide (Na₂O) in an approximate 1:1 molar ratio, providing an effective balance of alkalinity and surface protection. The pentahydrate form contains water of crystallization, which enhances product stability, handling characteristics, and performance consistency. Wyoming Chemical Distribution partners with trusted manufacturers to provide reliable product quality and dependable supply solutions for customers across diverse industries.
Properties & Advantages
- White and free-flowing granules or powder.
- Dissolves easily, even in cold water.
- High bulk density with low dust content.
- Negligible insoluble residues ensure product purity.
- As a highly alkaline product, Sodium Metasilicate readily reacts with CO2. Our advanced production methods minimize the risk of partial inactivity caused by CO2 contamination, as there is no contact between our products and combustion gases. This ensures a consistently pure and active Sodium Metasilicate.
