Sodium metasilicate non-hydrate is the non-hydrate form of sodium metasilicate. Sodium metasilicate (chemical formula: Na2SiO3) is a kind of sodium silicate, appearing as a powdered or flaked solid. It is used in cements, passive fire protection, textile and lumber processing, refractories, and automobiles. It has various kinds of applications. The major applications are in detergents, paper, water treatment, and construction materials as well as dye auxiliary. In addition, it also has many niche and hobby applications such as used in food preservation, metal repair, automotive repair, home-brewing, aquaculture and pottery. It is manufactured through the reaction between sodium carbonate and silicon dioxide.
Silicon (Si) has been reported to effectively manage some pests and diseases of plants.Exogenous application of silicon (Si) in the form of sodium metasilicate reduced disease development caused by Penicillium expansum and Monilinia fructicola in sweet cherry fruit at 20 degrees C. The inhibition of fruit decay was correlated closely with Si concentrations.
