What is Boron?

  • Boron is a chemical element with atomic number five and it is a trace element that is found in the earth’s crust and solar system. Boron is a metalloid.

Uses of Boron

  • Sodium tetraborate decahydrate or borax is the most important compound of boron, which is used to insulate fiber glass and sodium perborate bleach.
  • Boric acid is one of the important compounds in textile products. Boron compounds are also used in organic synthesis, in a particular type of glass manufacture and as a wood preservative.
  • Borax was earlier used to make perborate, which is the bleaching agent widely used in some detergents.
  • Boron compounds are also found in homes in the form of food preservatives, especially for fish and margarine.

Properties of Boron

  • It’s a poor conductor of electricity and can also be found in ceramics, flare guns, and fiber glasses.
  • Boron has several forms such as amorphous boron which is a dark powder and it is non-reactive to oxygen, water, alkalis, and acids are the most common. It forms borides when it reacts with metals.

Certain Facts About Boron

  • Boron is present over a hundred minerals on Earth. But it is extremely difficult to produce, even in laboratory conditions.
  • Boromycin is a boron-based natural antibiotic. It is a derivative of Streptomyces.
