What is the Boron ?

Boron is charcoal-grey pieces or black powder, while it's Molecular Formula is B. Boron is used to harden metals and as an oxygen scavenger for copper and other metals. It is used as a reinforcing material for composites. Boron filaments are used for lightweight but highstrength building materials for aerospace structures, golf clubs, and fishing rods. Amorphous boron can produce a green flare, and is therefore useful in pyrotechnic flares. Boron is also used in the production of borosilicate glass, which is highly resistant to thermal shock. An alloy of boron, iron, and neodymium is used to create a permanent magnet, known as the neodymium magnet. These magnets are used in magnetic resonance imaging machines, cell phones, and CD and DVD players. Boron is also employed as a catalyst in olefin polymerization and alcohol dehydration. Some boron compounds are used in the production of insulating fiberglass, bleach, adhesives, bulletproof vests, and tank armor. The principal consumption pattern in the United States for boron is for the production of glass products with minor usage in the production of soaps and detergents.

What is Boron (7440-42-8) used for?

Boron was discovered by Sir Humphry Davy and J.L. Gay-Lussac in 1808. It is a trivalent non-metallic element that occurs abundantly in the evaporite ores borax and ulexite. Boron is never found as a free element on Earth. Boron appears as charcoal-grey pieces or black powder or as crystalline; is a very hard, black material with a high melting point; and exists in many polymorphs. Boron has several forms, and the most common one is amorphous boron, a dark powder, non-reactive to oxygen, water, acids, and alkalis. It reacts with metals to form borides. Boron is an essential plant micronutrient. Sodium borate is used in biochemical and chemical laboratories to make buffers. Boric acid is produced mainly from borate minerals by the reaction with sulphuric acid. Boric acid is an important compound used in textile products. The most economically important compound of boron is sodium tetraborate decahydrate or borax, used for insulating fibreglass and sodium perborate bleach. Compounds of boron are used in organic synthesis, in the manufacture of a particular type of glasses, and as wood preservatives. Boron filaments are used for advanced aerospace structures, due to their high strength and light weight.
