Boron’s most common use is in compounds such as Boric acid and Borax which are used in antiseptics, washing powders and glazes. It has been used since 300AD as a decorative glaze for tiles in Italy due to its colour and it is easily mixed with other compounds. Pure Boron is hard to isolate and it is most commonly found in ores in the earth’s crust or in compounds. This is because Boron with easily bond with Carbon producing carbon based compounds. It was isolated first in 1808 by Humphry Davy, Joseph Louis Gay Lussac and Louis Jacques Thenard who isolated it from the reaction of Potassium and Boric acid. It is located in Group 13. It is a solid at room temperature and it has a melting point of 2075°c and a boiling point of 4000°c. Boron is a solid at room temperature and exists as two allotropes.
