Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called water glass, water glass, or liquid glass. The product has a wide variety of uses, including the formulation of cement, passive fire protection, textile and lumber processing, manufacture of refractory ceramics, as adhesives, and the production of silica gel. The commercial product, available in water solution or in solid form, is often greenish or blue owing to the presence of iron-containing impurities.
Uses of Sodium silicate ((Na2O)x·SiO2)
Sodium silicate is used in wastewater treatment plants as an iron flocculant and an alum coagulant.
It is used hand-dyeing as a fixative.
It is used in Pottery.
It is widely used in food preservation, homebrewing, and aquaculture.
Drilling fluids
Sodium silicate is frequently used in drilling fluids to stabilize borehole walls and to avoid the collapse of bore walls. It is particularly useful when drill holes pass through argillaceous formations containing swelling clay minerals such as smectite or montmorillonite.
Concrete and general masonry treatment
Concrete treated with a sodium silicate solution helps to reduce porosity in most masonry products such as concrete, stucco, and plasters. This effect aids in reducing water penetration, but has no known effect on reducing water vapor transmission and emission. A chemical reaction occurs with the excess Ca(OH)2 (portlandite) present in the concrete that permanently binds the silicates with the surface, making them far more durable and water repellent. This treatment generally is applied only after the initial cure has taken place (7 days or so depending on conditions). These coatings are known as silicate mineral paint.
Detergent auxiliaries
It is used in detergent auxiliaries such as complex sodium disilicate and modified sodium disilicate. The detergent granules gain their ruggedness from a coating of silicates.
Water treatment
Sodium silicate is used as an alum coagulant and an iron flocculant in wastewater treatment plants. Sodium silicate binds to colloidal molecules, creating larger aggregates that sink to the bottom of the water column. The microscopic negatively charged particles suspended in water interact with sodium silicate. Their electrical double layer collapses due to the increase of ionic strength caused by the addition of sodium silicate (doubly negatively charged anion accompanied by two sodium cations) and they subsequently aggregate. This process is called coagulation.
Sand casting
It is used as a binder of the sand when doing sand casting of iron or steel. It allows the rapid production of a strong mold, bypassing CO2 through the mixture of sand and sodium silicate in the mold box, which hardens it almost instantly.
Dye auxiliary
Sodium silicate solution is used as a fixative for hand dyeing with reactive dyes that require a high pH to react with the textile fiber. After the dye is applied to a cellulose-based fabric, such as cotton or rayon, or onto silk, it is allowed to dry, after which the sodium silicate is painted onto the dyed fabric, covered with plastic to retain moisture, and left to react for an hour at room temperature.
Metal repair
Sodium silicate is used, along with magnesium silicate, in muffler repair and fitting paste. When dissolved in water, both sodium silicate and magnesium silicate form a thick paste that is easy to apply. When the exhaust system of an internal combustion engine heats up to its operating temperature, the heat drives out all of the excess water from the paste. The silicate compounds that are left over have glass-like properties, making a temporary, brittle repair.
Pottery
Sodium silicate is used as a deflocculant in casting slips helping reduce viscosity and the need for large amounts of water to liquidize the clay body. It is also used to create a crackle effect in pottery, usually wheel-thrown. A vase or bottle is thrown on the wheel, fairly narrow and with thick walls. Sodium silicate is brushed on a section of the piece. After 5 minutes, the wall of the piece is stretched outward with a rib or hand. The result is a wrinkled or cracked look.
Food and medicine
While not actually a medical use, sodium silicate, and other silicates, are the primary components in "instant" wrinkle remover creams, which temporarily tighten the skin to minimize the appearance of wrinkles & under-eye bags. These creams, when applied as a thin film and allowed to dry for a few minutes, can present dramatic results. Unfortunately, it is not permanent, lasts few minutes or a couple of hours. It works like water-cement, once the muscle starts to move, it cracks and leaves white residues on the skin.
