Usage

Uses

Used in Wastewater Treatment:
Sodium metasilicate nonahydrate is used as a component in the preparation method and application of Cationic Polyacrylamide modified Silicon Dioxide/Calcium Inosilicate material. This application aids in the treatment of wastewater, making it a valuable resource in the environmental sector.
Used in Plant Protection:
In agriculture, sodium metasilicate nonahydrate is used as a source of silicon (Si) for managing pests and diseases in plants. The exogenous application of silicon in the form of sodium metasilicate has been reported to reduce disease development caused by Penicillium expansum and Monilinia fructicola in sweet cherry fruit at 20 degrees Celsius. The inhibition of fruit decay is closely correlated with Si concentrations, making it an effective tool in plant protection.
Used in Detergents, Paper, Water Treatment, and Construction Materials:
Sodium metasilicate nonahydrate is widely used in various industries such as detergents, paper production, water treatment, and construction materials. Its properties make it suitable for a range of applications, including as a dye auxiliary and in the production of cements, passive fire protection, textile and lumber processing, and refractories.
Used in Food Preservation, Metal Repair, Automotive Repair, Home-Brewing, Aquaculture, and Pottery:
Sodium metasilicate nonahydrate also has numerous niche and hobby applications. It is used in food preservation to extend the shelf life of products, in metal repair to clean and protect surfaces, in automotive repair for cleaning and corrosion protection, in home-brewing to clarify beer, in aquaculture for water treatment, and in pottery to create a durable and water-resistant glaze on ceramic surfaces.
