Borax Anhydrous

MGCP Borax Anhydrous

Borax Anhydrous is a product resulting from the dehydration and fusion of borax. It is a hard, glassy material, granular in texture. Borax Anhydrous does not rehydrate under ordinary storage conditions, and can be handled in bulk. It is an excellent flux and glass former. In aqueous solution it can provide slow release of boron. Using Borax Anhydrous can help to increase yields, reduce energy consumption, and control emissions of Boron Oxide(B2O3) in glass, ceramic and enamel frit production.


Borax Anhydrous is used as a source of B2O3 in the manufacture of many different types of borosilicate glass, including heat and chemical resistant glasses, illumination glasses, optical lenses, medical and cosmetic containers, hollow microspheres and glass beads. In the manufacturing process Borax Anhydrous has advantages over borax (5 and 10 mol) having a higher bulk density and melting more rapidly with minimum energy. It can reduce furnace emission and increase production. It also provides a source of sodium and can be used with boric acid or Boron Oxideto control the sodium oxide/Boron Oxideratio in the glass.

B2O3 acts as both a flux and network former and is used to formulate glasses with low thermal expansion (high thermal shock resistance) and good chemical durability.

Frits, glazes and enamels

Glazes and enamels provide decorative and protective coatings for ceramics (wall and floor tiles, tableware and porcelain) and metals (plumbing fixtures, cookware and appliances). As in the case of glass, B2O3 allows the formulation of low melting glazes and enamels with the correct thermal expansion. In enamels the borate improves adhesion to the metal by dissolving iron oxide and reducing the melt surface tension.


Borax Anhydrous is an excellent solvent for metallic oxides at high temperatures. In the field of metallurgy, Borax Anhydrous is used as a cover flux to protect metal surfaces from air oxidation. Borax Anhydrous also serves as a scavenger to dissolve metallic oxides and other contaminants in the production of ferrous and non-ferrous metals. Since boron is regarded as a unique and highly versatile alloying element in steel, Borax Anhydrous can be used to improve the properties and processing behavior of steel products.

Cleaning products

Borax Anhydrous is used in the formulation of slow-dissolving cleaning briquettes that are based on gelled or solidified borate suspensions. For example, in toilet bowl cleaners, the slow release of borate softens water to prevent scale build-up, while deodorizing, and inhibiting stain formation.


Borate compounds are used as stabilizers and bonding agents in firebricks and castables. Borax Anhydrous gives an intermediate-temperature glassy bond prior to the establishment of the ceramic bond, at which point the borate compound is frequently volatilized from the system.

Enhanced oil recovery

Being effective cross-linking agents, borates are finding increasing uses in the oil industry. High viscosity oil-well fluids made from the reaction between Borax Anhydrous and polymers are utilized to increase the recovery of oil from subterranean formations.
