Boric Acid (H3BO3)

CAS Number: 10043-35-3

Technical Grade: Granular and Powder

Packaging: 25 kg, 50 kg, 1000 kg (with or without pallet)

Usage and Benefits:

Glass: Boric acid is used in the production of special type glasses (oven glasses, glass laboratory materials, etc.) and glass fiber. It prevents devitrification in glass production. It increases the resistance of glass against heat, chemicals, and mechanical impacts. Boric acid is used in the production of single-filament fiberglass (textile-grade glass fiber). Higher and more consistent B2O3 levels when compared to colemanite, which is another material used for producing textile grade glass fiber; lack or refractory mineral content (such as Mg, Si, Al, Fe, St, S and As) and low melting point make boric acid more useful. It increases fiberizing in isolation and reinforcement fiber glasses by reducing viscosity. Moreover, it increases the physical and humidity resistance of fibers by reducing their tendency to crystallize.

Ceramics: Boric acid is used as a binder in ceramics. As a result of the addition of boric acid, melting and adhesion occur at lower temperatures. It enhances the resistance of ceramic products to breakage and scratches in the face of physical impacts and strengthens their chemical resistance. It is used in glazing and enamel coating where sodium is not desired in the formulations. Furthermore, it is used as a reinforce in the production of ceramic wet tiles. It improves condensation properties in porcelain tiles by increasing the vitrification temperature. It is one of the materials used in the production of ceramic and porcelain enamel frit.

Detergent: Boric acid is used as a germicide and bleaching agent. It can be added to soap and detergents due to its water-softening and germicide properties. It has the effect of reducing the washing time and temperature.

Agriculture: Boron is one of the nutrients required by plants. It plays an important role in plant yield, flowering and pollen production and seed development. Boric acid can be used alone or in combination with standard fertilizers in soils with low boron content. It is used in the production of disodium octaborate tetrahydrate, which is used as a boron fertilizer in agriculture, and in the production of herbicides.

Fire retardant: Boric acid is the basic form of borate-based fire retardants which are used to reduce the kindling rate of burning substances. In the recent years, it has become important for giving fire retardant properties to resin-based wooden composite panels and for being used as a protective material in timber and solid wooden products. It can be used together with disodium octaborate tetrahydrate as flame retardant material in wooden composite materials, marine, yacht and aviation coatings. It is added to fire bricks and mortars to provide resistance against heat or corrosion.

Nuclear energy: It is used for neutron retention in nuclear power plants for reducing the rate of neutron fission generation. Natural boron contains 20% 10B and approximately 80% 11B. 10B has a high cross-sectional area for the retention of low-energy neutrons. When more boric acid is added to the reactor cooler and is allowed to circulate inside the reactor, the probability of neutron fission is reduced. Therefore, boric acid can effectively control the fission rate inside the reactor. This method is utilized in Pressurized Water Reactors. Boric acid is also used for keeping the neutron multiplication under control in spent fuel pools containing uranium rods.

Wood protection: Boric acid is used as a protective agent against rotting on dry or wet wooden surfaces. It can also be applied as gel or solution on wooden surfaces. Protective agents with borate compounds are successfully used in marine industry against factors such as moss, fungi and ooze.

Medicine: Boric acid can be used as an antiseptic. Dilute solutions of boric acid can be used as eye-washing solutions. Dilute boric acid solution is also used as an anti-bacterial agent. It can be used for the treatment of external otitis in solution form.

Anti-bacterial agent and for cleaning: In industry, it is used as an anti-corrosive and anti-bacterial material in metal coating processes. It is also used in the production of boron-based herbicide and artificial fertilizer. Sodium perborate, which is used as an oxidizing and bleaching material in cleaning products, is obtained from boric acid. Lubrication: The colloidal suspensions of boric acid form a good lubricant for ceramic and metal surfaces when they are added to petroleum and vegetable oils and they significantly reduce the friction coefficient.

Various industrial productions: In the petrochemical industry, it catalyses the oxidation of hydrocarbons in the production of Nylon 66 and increases the efficiency of the conversion of hydroxyl groups into alcohols with further oxidation. It is used in the production of ferro[1]boron which is used in the production of steel, casting, neodymium[1]iron-boron magnets and amorphous metals. In metallurgical operations, it reduces the energy consumption by having a positive effect on the fusing temperature; enables the durability of steel to increase and has a plasticizing function when used as a slag-former. It provides support and extra bonding to strength in the steel, glass, cement, and aluminium industries. Adding boric acid to papier-mache increases the strength of papier-mache panels, reduces their weight and prevent wrinkling on their surfaces. It plays a role as an enzyme stabilizer in liquid laundry detergents. Boric acid is used as a peptizer in the production of adhesives containing casein and dextrin based starch.
