Uses of Boric Acid

Boric acid is a weak acid that is made up of boron, hydrogen and oxygen. It is a solid white crystal substance at room temperature and can be dissolved in water. Boric acid can be found in nature in some areas of volcanic activity as well as in seawater, plants and fruits. It was first prepared by Dutch scientist Wilhelm Homberg from borax, but was known and used in Ancient Greece for a variety of purposes. Most boric acid made today is prepared by reacting borax with a mineral acid (usually hydrochloric acid). It is a relatively safe acid and it is used for a variety of applications. Uses of boric acid Boric acid has many uses in the medical industry. It is used as an antiseptic for minor cuts and burns and it is sometimes added to dressings. It can also be used to treat certain bacterial and fungal infections, such as acne and athlete’s foot. Overuse can cause a build up in the system and be toxic, especially for infants and small children. Boric acid is a popular insecticide and can be used to kill a verity of household pests such as ants, termites, fleas, cockroaches, silverfish and many other small insects. It kills the insects by disturbing their metabolism and is abrasive to their exoskeletons. Boric acid is used to treat wood to prevent termites and to prevent wet and dry rot. It is also combined with ethylene glycol to treat external wood against fungal infections or insects. Boric acid gel and paste can also be used to insert into rotting timber to treat it instead of replacing it. Boric acid based treatments can be used to prevent slime and algae growth. Boric acid, together with common salt, is used in the curing process from sheepskins, calfskins and cattle hides. It helps to stop bacteria from growing on the hides and controls insects. Boric acid, together with petroleum or vegetable oil, is a very suitable lubricant for metal or ceramic surfaces. Boric acid is used as a neutron poison to slow down the rate of fission in nuclear power plants. Boric acid was dumped on the reactor at the Chernobyl Nuclear Power Plant after meltdown to prevent any further reactions! Boric acid is used in the production of textile fiberglass and in the production of certain types of furnace linings and ceramics. It is used in the jewelry industry to reduce unwanted marking from occurring on the metals during construction. Boric acid can be used to make fire green, which is the method used by fire jugglers and spinners. It can also be used in fireworks to prevent a reaction between aluminum and nitrates. It also has many other uses such as: in the production of LCD displays, in the manufacture of Silly Putty, neutralizing hydrofluoric acid, a fire retardant for wood, electroplating and many more.
Latest company new about A typical Belousov-Zhabotinsky pattern of concentric circles, observed in this case in polymer-controlled crystallisation and self-organisation from barium carbonate.

A typical Belousov-Zhabotinsky pattern of concentric circles, observed in this case in polymer-controlled crystallisation and self-organisation from barium carbonate.

     A typical Belousov-Zhabotinsky pattern of concentric circles, observed in this case in   polymer-controlled crystallisation and self-organisation from barium carbonate. The   structures are similar to a computer-simulated pattern (smaller circle, upper right). The   block copolymer used appears in the picture as a shortened molecule structure.          In order to survive, biological systems need to form patterns and organise   themselves. Scientists at the Max Planck Institute for Colloids and Interfaces in   Potsdam, Germany, have now combined self-organisation with chemical pattern   formation.They coupled an oscillating chemical reaction with polymer-controlled   crystallisation and self-organisation in barium carbonate. In this way, they proved that   oscillating reactions - like the renowned Belousov-Zhabotinsky reaction - can also take   place in multi-phase systems.     On basis of these results, scientists can better explain chemical reactions which are   out of thermodynamic balance, as well as biological pattern formation in nature.   Furthermore, these results could lead to the creation of surfaces with new kinds of   structures (Angewandte Chemie, June 21, 2006).   Scientists are especially interested in oscillating chemical reactions. These occur when   reaction products periodically and repeatedly change. Their behaviour is of importance   to many fields of study - including chaos research. That is because these reaction   systems are always complex and far away from thermodynamic equilibrium. One   particularly well-known example is the "Belousov-Zhabotinsky" reaction. In it, a   coloured indicator is used to make the reaction products of a coupled redox reaction   visible. They typically take on the pattern of concentric circles, spreading out, for   example, across a petri dish.      Mathematically, spatially oscillating reactions can be described as "reaction-diffusion   systems". This means that it is not just chemical reactions which influence the amount   of material at a certain point in space. Diffusion also plays a role - the exchange of   material with the surrounding area. In such simulations, we get the typical concentric   circle pattern of a Belousov-Zhabotinsky reaction. In the picture above, it is indicated in   red-violet.      Researchers from Potsdam have now proven that these oscillating reactions can   also apply to multi-phase systems, and even to the self-organisation processes of   nanoparticles. What is central is that in a multi-phase reaction system, it is possible to   formulate either an autocatalyic or autoinhibiting reaction step. This leads an oscillating   system to be constructed, and ultimately a pattern to be formed.       The researchers used a newly synthesized polymer to create the typical concentric   circle pattern, via controlled barium carbonate crystallisation (see image). Such   patterns correspond quite well to the calculations in a simulation. The researchers also   were able to formulate a complex coupled reaction system including crystallisation,   complexation, and precipitation reactions and identify the autocatalytic formation of a   complex between barium and the polymer.       Notably, the elongated crystalline structures which made up the circular pattern are   themselves created by superstructures of nanoparticles, which are themselves created   by self-organisation (see image). In this way, Max Planck researchers have shown for   the first time that the Belousov-Zhabotinsky reaction does not just take place in a   solution, but also in multi-phase systems, and in nanoparticle self-organisation. This   discovery is not only important to research into reactions far away from thermodynamic   equilibrium. It can also help explain biological pattern formation. One example of   biological self-organisation is mussel shell patterns. They are created via controlled   crystallisation, just like the model systems of the researchers in Potsdam used.         Interestingly, these patterns also mathematically duplicate reaction-diffusion systems   exactly.
