Sodium Metasilicate 9H₂O is a highly useful inorganic alkaline silicate widely used in industrial cleaning, detergent manufacturing, metal treatment, water treatment, textile processing, pulp and paper, and other chemical applications. Its strong alkalinity, excellent cleaning capability, buffering action, and detergent-building properties make it an important raw material for numerous industrial formulations.
Sodium Metasilicate 9H₂O is a hydrated form of sodium metasilicate containing nine molecules of water of crystallization. It is commonly represented by the chemical formula Na₂SiO₃·9H₂O.
It is generally supplied as a white crystalline solid or granular material and dissolves in water to form an alkaline solution. Because of its silicate content and alkalinity, it can provide cleaning, buffering, dispersing, and water-conditioning properties in appropriately designed formulations.
Sodium Metasilicate 9H₂O is an effective component in heavy-duty industrial cleaning formulations. Its alkaline nature helps loosen and remove grease, oil, dirt, and other industrial contaminants from hard surfaces.
It can be used in formulations for machinery, equipment, workshops, industrial floors, and processing areas.
One of the major applications of Sodium Metasilicate 9H₂O is as a detergent builder.
It can support cleaning performance by helping manage the effects of water hardness and improving the overall effectiveness of surfactant-based formulations. It is suitable for selected powder and liquid cleaning formulations depending on formulation requirements.
Sodium Metasilicate 9H₂O can be incorporated into alkaline metal-cleaning formulations to help remove oil, grease, dirt, and processing residues from metal components.
It can be particularly useful during pre-treatment operations before painting, coating, or other surface-finishing processes.
Sodium metasilicate-based alkaline cleaners are used in selected marine and ship-maintenance cleaning formulations.
They can help clean oil, grease, and general contamination from machinery spaces, workshops, decks, and other hard surfaces. Formulation compatibility should always be checked for specific metals, coatings, and marine equipment.
Sodium metasilicate compounds can be used in selected industrial water-treatment applications because of their alkaline and silicate characteristics.
Depending on the treatment process, they may assist with pH control, buffering, dispersion, and interaction with certain dissolved or suspended materials.
Sodium Metasilicate 9H₂O can be used in certain textile processing and cleaning formulations where an alkaline environment is required.
It can help remove oils, dirt, and processing residues and can support the performance of other cleaning ingredients.
Sodium metasilicate is used in selected pulp and paper processing formulations where alkaline conditions, cleaning, stabilization, or silicate functionality are beneficial.
Because of its alkaline properties, Sodium Metasilicate 9H₂O can be an important ingredient in industrial degreasers designed for removing heavy oil and grease contamination.
When combined with suitable surfactants, chelating agents, builders, and other formulation ingredients, it can contribute to enhanced cleaning performance.
Its alkaline character helps loosen and remove oily and greasy contamination from suitable surfaces.
Sodium Metasilicate 9H₂O can enhance the performance of cleaning formulations and support effective soil removal.
It can help reduce the negative effects of hard water in selected detergent and cleaning systems.
It assists in keeping loosened contaminants dispersed in the cleaning solution, helping reduce redeposition.
Its combination of alkalinity and silicate functionality makes it useful across multiple industrial sectors.
The primary difference is the amount of water of crystallization.
Sodium Metasilicate 9H₂O: Na₂SiO₃·9H₂O
Sodium Metasilicate Pentahydrate: Na₂SiO₃·5H₂O
Because their hydration levels and molecular weights are different, the required quantity may differ when replacing one grade with another in a formulation.
Manufacturers should calculate dosage based on the required active sodium metasilicate concentration rather than simply replacing products on a weight-for-weight basis.
Sodium Metasilicate 9H₂O should be stored in a dry, cool, and well-ventilated location. Keep the material protected from moisture and stored in properly sealed packaging.
During handling, appropriate personal protective equipment should be used because the material produces an alkaline solution when dissolved in water. Refer to the manufacturer's SDS and technical data sheet for detailed safety and handling requirements.
Industrial buyers should consider several factors when selecting a Sodium Metasilicate 9H₂O supplier, including:
Consistent product quality
Required purity and grade
