Sir Humphry Davy discovered the element in 1808 after observing its special characteristics while working with boric acid. The Latin word for food, boris, is where the element's name originates.

The most typical boron-containing minerals are tourmaline,ulexite and kernite.Additionally, deposits of coal and petroleum contain boron.Turkey is home to the largest known boron deposit in the world.Numerous industrial applications involve the use of boron.Doping semiconductors is one of its main applications.N-type semiconductors, a crucial component in the production of electronic devices like transistors and diodes, are made from silicon that has been boron-doped.Additionally, glass and ceramics use boron as an additive.It is added to glass to increase durability and heat resistance.Ceramics containing boron are employed in a number of products, including bulletproof clothing and electrical insulation.

Another significant commercial product that contains boron is boric acid, which is created when boron reacts with water. Insecticide, wood preservative, and fire retardant are all uses for boric acid. Additionally, it has some medical uses, including the treatment of osteoarthritis.
