The boron is indicated in the periodic table with B symbol and its atom number is 5 and the atomic weight is 10,81. The boron element, which has semi-metallic and semi-conductive properties, is contained in group 3A of the periodic table. Boron consists of two stable isotopes, called B10 and B11 in nature. The rate of the B10 isotope to be found in the nature is 19,1-20,3%, and 79%, 80,9% for B11.
The boron element, which is never found free in nature, forms compounds with different properties with various metals or non-metal elements. In this regard, many boron compounds are used in different branches of the industry. In boron compounds, it behaves like non-metal compounds. Pure boron possesses electrical conductivity like carbon. Crystallized boron is similar in appearance and optical properties and almost as hard as diamond. First pure Boron was discovered for the first time in 1808 by French chemist J.L. Gay – Lussac and Baron L.J. Thenard and English Chemist H. Davy.
