Sodium metasilicate pentahydrate

White crystalline solid, soluble in water.

Sodium metasilicate pentahydrate is a white crystalline solid that readily dissolves in water. It has a melting point of around 108°C and is used in various industrial applications, such as detergents, ceramics, and construction materials. It can also be used as a source of silica in the production of insulating materials for the energy sector.

Energy Sector

Sodium metasilicate pentahydrate is used in the energy sector as a fluid thinner, drilling fluid stabilizer, and as a source of silica in cementing operations. Its unique properties make it an effective dispersant for clay and other impurities found in drilling muds. It is also used in the production of ceramic proppants, which are small particles added to hydraulic fracturing fluids to prop open fractures and enhance oil and gas production from shale formations.

Water Treatment

Sodium metasilicate pentahydrate is commonly used in water treatment as a coagulating and flocculating agent, helping to remove impurities and particles from water. It is also used to adjust the pH of water and to soften hard water by removing calcium and magnesium ions. Additionally, it can be used in the production of water treatment chemicals, such as silica gel and zeolites, which can help remove heavy metals and other pollutants from water sources. Sodium metasilicate pentahydrate is a versatile material in the field of water treatment due to its ability to improve water quality in various ways.

Pulp & paper

Sodium metasilicate pentahydrate is used in the pulp and paper industry as a bleaching agent and as a dispersant to prevent the buildup of pitch and other contaminants on equipment. It is also used as a sizing agent to increase the strength and water resistance of paper products. Sodium metasilicate pentahydrate can also be used as a deinking agent to remove ink from recycled paper. Its versatility and effectiveness make it a valuable component in the production of high-quality paper and related products.
