Industrial grade boric acid 99%min purity used for glass
Boric acid (orthoboric acid) is a weakly acidic hydrate of boric
oxide with mild antiseptic, antifungal, and antiviral properties.
Boric acid can be used to treat yeast infections and acne, for
eyewash by treating any bacterial infection and soothing inflamed
eyes, and as a cleanser, deodorizer, stain remover, disinfectant
and mold killer. Boric acid can be used as a pesticide to control a
variety of pests, as a fungicide for citrus, and as an herbicide
along rights-of-way. Boric acid can be used for the manufacture of
textile fiberglass, household glass products and the glass used in
LCD displays, to reinforce plastics in various products (boats,
computer circuit boards and pipes), as a flame retardant, and as a
pH buffer agent in plating.

The primary industrial use of boric acid is in the manufacture of
monofilament fiberglass usually referred to as textile fiberglass. Textile fiberglass is
used to reinforce plastics in applications that range from boats,
to industrial piping to computer circuit boards.
In the jewelry industry, boric acid is often used in combination
with denatured alcohol to reduce surface oxidation and firescale from forming on metals during annealing and soldering operations.
Boric acid, mixed with borax (sodium tetraborate decahydrate) at
the weight ratio of 4:5, is highly soluble in water, though they
are not so soluble separately.The solution is used for fire
retarding agent of wood by impregnation.
It is also used in the manufacturing of ramming mass, a fine silica-containing powder used for producing induction furnace linings and ceramics.
Boric acid is one of the most commonly used substances that can
neutralize active hydrofluoric acid (HF). It works by forcing the free F− anions into complex salts. This process defeats the extreme
toxicity of hydrofluoric acid, particularly its ability to
sequester ionic calcium from blood serum which can lead to cardiac
arrest and bone decomposition; such an event can occur from just
minor skin contact with HF.
Boric acid is added to borax for use as welding flux by blacksmiths.
Boric acid, in combination with silicone oil, is used to manufacture Silly Putty.
Boric acid may be used in Marcellus Shale hydraulic fracturing in Pennsylvania.
Boric acid can be used as an antiseptic for minor burns or cuts and is sometimes used in salves and dressings, such as boracic lint. Boric acid is applied in a very dilute solution as an eye wash.
Dilute boric acid can be used as a vaginal douche to treat bacterial vaginosis due to excessive alkalinity,as well as candidiasis due to non-albicans candida. As an antibacterial compound, boric acid can also be used as an acne treatment. It is also used as prevention of athlete's foot, by inserting powder in the socks or stockings, and in alcohol
solution can be used to treat some kinds of otitis externa (ear infection) in both humans and animals. The preservative in urine sample bottles in the UK is boric acid.
Boric acid solutions used as an eye wash or on abraded skin are
known to be toxic, particularly to infants, especially after
repeated use; this is because of its slow elimination rate.
Boric acid was first registered in the US as an insecticide in 1948
for control of cockroaches, termites, fire ants, fleas, silverfish, and many other insects. The product is generally considered to be safe to use in
household kitchens to control cockroaches and ants. It acts as a
stomach poison affecting the insects' metabolism, and the dry powder is abrasive to the insects' exoskeletons. Boric acid also has the reputation as "the gift that keeps on
killing" in that roaches that cross over lightly dusted areas do
not die immediately, but that the effect is like shards of glass
cutting them apart. This often allows a roach to go back to the
nest where it soon dies. Cockroaches, being cannibalistic, eat others killed by contact or consumption of boric acid,
consuming the powder trapped in the dead roach and killing them,
too. The cycle continues until the boric acid has more-or-less been
exhausted or the queen herself has consumed some, killing her,
which destroys the colony.
In combination with its use as an insecticide, boric acid also
prevents and destroys existing wet and dry rot in timbers. It can
be used in combination with an ethylene glycol carrier to treat external wood against fungal and insect attack.
It is possible to buy borate-impregnated rods for insertion into
wood via drill holes where dampness and moisture is known to
collect and sit. It is available in a gel form and injectable paste
form for treating rot affected wood without the need to replace the
timber. Concentrates of borate-based treatments can be used to
prevent slime, mycelium, and algae growth, even in marine
Boric acid is added to salt in the curing of cattle hides, calfskins, and sheepskins. This helps to control bacterial development, and helps to control
Colloidal suspensions of nanoparticles of boric acid dissolved in
petroleum or vegetable oil can form a remarkable lubricant on
ceramic or metal surfaces with a coefficient of sliding friction
that decreases with increasing pressure to a value ranging from
0.10 to 0.02. Self-lubricating H3BO3 films result from a spontaneous chemical reaction between water
molecules and B2O3 coatings in a humid environment. In bulk-scale, an inverse
relationship exists between friction coefficient and Hertzian
contact pressure induced by applied load.
Boric acid is used to lubricate carrom and novuss boards, allowing for faster play.
Boric acid is used in some nuclear power plants as a neutron poison. The boron in boric acid reduces the probability of thermal
fission by absorbing some thermal neutrons. Fission chain reactions
are generally driven by the probability that free neutrons will
result in fission and is determined by the material and geometric
properties of the reactor. Natural boron consists of approximately
20% boron-10 and 80% boron-11 isotopes. Boron-10 has a high
cross-section for absorption of low energy (thermal) neutrons. By
increasing boric acid concentration in the reactor coolant, the
probability that a neutron will cause fission is reduced. Changes
in boric acid concentration can effectively regulate the rate of
fission taking place in the reactor. Boric acid is used only in pressurized water reactors (PWRs) whereas boiling water reactors (BWRs) employ control rod pattern and coolant flow for power
control. BWRs use an aqueous solution of boric acid and borax or
Sodium Pentaborate for an emergency shut down system. Boric acid
may be dissolved in spent fuel pools used to store spent fuel
elements. The concentration is high enough to keep neutron
multiplication at a minimum. Boric acid was dumped over Reactor 4
of the Chernobyl Nuclear Power Plant after its meltdown to prevent another reaction
Boric acid is used to treat or prevent boron deficiencies in plants. It is also used in preservation of grains such as rice
