Production
The production of boron compounds does not involve formation of elemental boron, but exploits the convenient availability of borates.
The earliest routes to elemental boron involved reduction of boric oxide with metals such as magnesium or aluminium. However the product is almost always contaminated with metal borides. Pure boron can be prepared by reducing volatile boron halides with hydrogen at high temperatures. Ultrapure boron, for the use in semiconductor industry, is produced by the decomposition of diborane at high temperatures and then further purified with the zone melting or Czochralski processes.

Famous quotes containing the word production:
“The problem of culture is seldom grasped correctly. The goal of a culture is not the greatest possible happiness of a people, nor is it the unhindered development of all their talents; instead, culture shows itself in the correct proportion of these developments. Its aim points beyond earthly happiness: the production of great works is the aim of culture.”
—Friedrich Nietzsche (1844–1900)
“Every production of an artist should be the expression of an adventure of his soul.”
—W. Somerset Maugham (1874–1965)
“Perestroika basically is creating material incentives for the individual. Some of the comrades deny that, but I can’t see it any other way. In that sense human nature kinda goes backwards. It’s a step backwards. You have to realize the people weren’t quite ready for a socialist production system.”
—Gus Hall (b. 1910)
