boron atomic number 5 ne atomic mass 11 Boron ielement rinonetsa rinonyanyowanikwa mumasupernovuea.Boron rinotorwa kubva kuma byrates. earliest routes to elemental boron involved the reduction of boric oxide with metals such as magnesium or aluminium. However, the product is almost always contaminated with borides of those metals. Pure boron can be prepared by reducing volatile boron halides with hydrogen at high temperatures. Ultrapure boron for use in the semiconductor industry is produced by the decomposition of diborane at high temperatures and then further purified with the zone melting or Czochralski processes.[22] The production of boron compounds does not involve the formation of elemental boron, but exploits the convenient availability of borates.
