Boron B (Element) PubChem

The element is not found free in nature, but occurs as orthoboric acid usually found in certain volcanic spring waters and as borates in boron and colemantie. Important sources of boron are ore rasorite (kernite) and tincal (borax ore). Both of these ores are found in the Mojave Desert. Tincal is the most important source of boron from the Mojave.

The reactions of boron are dominated by such requirement for electrons. Also, boron is the least electronegative non-metal, meaning that it is usually oxidized (loses electrons) in reactions. Boron is also similar to carbon with its capability to form stable covalently bonded molecular networks. Boron is also used for heat resistant alloys.

2018-8-26  A small amount of boron is used as a dopant in semiconductors, and reagent intermediates in the synthesis of organic fine chemicals. A few boron-containing organic pharmaceuticals are used or are in study. Natural boron is composed of two stable isotopes, one of which (boron-10) has a number of uses as a neutron-capturing agent.

Ore minerals

Titanium Usually produced from placer deposits, the ore minerals are rutile, ilmenite, and leucoxene. Tungsten Primary ore minerals are scheelite and huebnerite-ferberite. Uranium The chief primary ore minerals are uraninite, pitchblende (a mixture of various oxides), coffinite and a host of secondary minerals such as carnotite and autunite.

Boron production worldwide was 4.2 million tons in 2015, with 48% produced in Turkey. The most important commercial boron mineral colemanite (Ca2B6O11·5H 2 O) reserves are found in Hisarcık, in the Espey regionof Turkey. Large quantities of boron wastes are discharged during the processing of the ore in concentrators.

Boron compunds are usually is found in sediments and sedimentary rock formations. The chief sources of boron are Na 2 B 4 O 6 (OH) 2.3H 2 O known as rasorite or kernite; borax ore (known as tincal); and with calcium in colemanite (CaB 3 O 4 (OH) 4.H 2 O). Boron also occurs as orthoboric acid in some volcanic spring wa Isotopes:

Analyses of boronic ores and sludges and solubilities

1998-12-1  Most of the world's commercially recoverable reserves of boron are in the form of the hydrated borate minerals; colemanite (Ca 2 B 4 O 8.5H 2 O), pandermite (CaB 6 O 9.7H 2 O), ulexite (NaCaB 5 O 9.8H 2 O) and tincal (Na 2 B 4 O 7.10H 2 O). The boron is usually recovered as boric acid by leaching of the borate minerals.

Boron Corrosionsource

Boron exists naturally as 19.78% 10B isotope and 80.22% 11B isotope. High-purity crystalline boron may be prepared by the vapor phase reduction of boron trichloride or tribromide with hydrogen on electically heated filaments. The impure or amorphous, boron, a brownish-black powder, can be obtained by heating the trioxide with magnesium powder.
