What is the common name of sodium metasilicate?

Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass.

Is sodium metasilicate hazardous?

Sodium metasilicates are non-flammable, non-explosive, and non-toxic. They are, however, alkaline materials and pose hazards to the skin and eyes. The physiological effects of contact range from causing irritation to causing chemical burns. Sodium metasilicate should be handled with care.

What is the use of sodium metasilicate in detergent powder?

Sodium Silicate and Sodium Metasilicate Pentahydrate are used in industries producing several different types of detergent, because of its oil and grease removal and cleaning power, and because it is a buffering agent, helping in soil anti-redeposition and inhibiting process corrosion.

What is the function of sodium silicate?

Liquid sodium silicate reacts under acidic conditions to form a hard glassy gel. This property makes it useful as a bonding agent in cemented products such as concrete and abrasive wheels. It is also an excellent adhesive for glass or porcelain. A traditional use for dissolved water glass is as a preservative for eggs.

What products contain sodium metasilicate?

Sodium metasilicate is used in fireproofing mixtures; in laundry, dairy, metal, and floor cleaning; in deinking paper; in washing carbonated drink bottles; in insecticides, fungicides, and antimicrobial compounds; as a chemical intermediate for silica gel catalysts; as an additive in soaps and synthetic detergents; as.

What is the meaning of sodium silicate?

: any of various water-soluble substances obtained in the form of crystals, glasses, powders, or aqueous solutions usually by melting silica with a sodium compound (such as sodium carbonate or sodium hydroxide): such as.

How do you clean up sodium metasilicate?

Methods for cleaning up : Sweep or shovel spills into appropriate container for disposal. Precautions for safe handling : Avoid dust formation. Avoid contact with skin and eyes. Do not breathe dust.

Is sodium metasilicate natural?

Type: Naturally-derived.

What is the pH of sodium silicate?

The molar ratio between silica and sodium oxide (n) plays an important role in the chemical behavior of Na-silicate [11]. It is delivered commercially as a solution with a pH in the range of 11–13 and with a decrease in alkalinity of n.

Is sodium metasilicate soluble in water?


How is sodium silicate used in soap making?

Sodium Silicate solution is added to detergent shiny to help control reversion of the phosphates during the spray drying process. It also acts as binder to give the desired degree of “crispness” to the detergent bead without impairing its solubility in water.

How is sodium silicate used with cement?

Sodium silicate reacts with the calcium hydroxide in hydrated cement paste to form calcium-silicate-hydrate gel that fills cracks. It is observed that the microcapsule addition inhibits compressive strength development in cement and this is observed through a plateau in strength between 28 and 56 days.

How do you make sodium silicate?

The conventional process of manufacturing sodium silicate is by the reaction of silica sand with soda ash at about 1,100oC forming water glass, which is crushed & dissolved in water and digested under pressure with steam.

Is sodium silicate a mineral?

Sodium silicate minerals can form by evaporation of highly alkaline interstitial brines in near-surface horizons. The most common sodium silicates are magadiite, kenyaite and kanemite.

What household products contain sodium silicate?

Uses Adhesive. The largest application of sodium silicate solutions is a cement for producing cardboard. Drilling fluids. Concrete and general masonry treatment. Detergent auxiliaries. Water treatment. Refractory use. Sand casting. Dye auxiliary.

Is chloride A sodium?

Sodium chloride is the chemical name for salt. Sodium is an electrolyte that regulates the amount of water in your body. Sodium also plays a part in nerve impulses and muscle contractions. Sodium chloride is used to treat or prevent sodium loss caused by dehydration, excessive sweating, or other causes.

What type of salt is na2sio3?

Sodium metasilicate SODIUM SILICATE PubChem CID 23266 Molecular Formula Na 2 SiO 3 or Na 2 O 3 Si Synonyms Sodium metasilicate SODIUM SILICATE 6834-92-0 Waterglass Disodium metasilicate More Molecular Weight 122.063 Component Compounds CID 14768 (Metasilicic acid) CID 5360545 (Sodium).

How do you treat sodium silicate?

Sodium silicate can be hardened in a number of ways: by adding weak acids (CO2 gas or organic esters), by adding various powders (di-calcium silicate, anhydrite etc.), or by removing water. CO2 gas and liquid ester hardeners are the most widely used of the silicate processes.

How do you make silica gel from sodium silicate?

Sodium silicate that is formed is then hydrolysed to form silicic acid. Silica gel is formed from the condensation of silicic acid [10, 11]. In this study, synthesis of silica gel was carried out with glass base material and NaOH with citric acid catalyst at pH 5 and calcination temperature 400°C.

Is Potash a silicate?

Potassium silicate is the name for a family of inorganic compounds. The most common potassium silicate has the formula K2SiO3, samples of which contain varying amounts of water. These are white solids or colorless solutions.Potassium silicate. Names show InChI show SMILES Properties Chemical formula K 2 O 3 Si.

What is the name for Na2SiO3?

Sodium metasilicate.

Is sodium silicate hygroscopic?

Dry sodium silicates are hygroscopic products and adsorb water from the ambient air.

Is Na2SiO3 aqueous or solid?

A well-known member of this series is sodium metasilicate, Na2SiO3. Also known as waterglass or liquid glass, these materials are available in aqueous solution and in solid form.

Why would sodium silicate be added to drinking water?

Sodium silicates have been used in drinking water treatment for decades as sequestrants and corrosion inhibitors. These data suggest that, as a corrosion control treatment for lead, sodium silicate is inferior to orthophosphate in circumneutral pH water with low alkalinity.
