Boron fibers are used in lightweight composite applications, such as high strength tapes. This use is a very small fraction of total boron use. Boron is introduced into semiconductors as boron compounds, by ion implantation. [citation needed]
The borax deposit here was discovered in 1913, by John K. Suckow, [4] who when drilling for water found a deposit of what he believed to be gypsum. Further testing revealed it was the colemanite form of borax. Francis Marion "Borax" Smith bought the claim for his Pacific Coast Borax Company. [5] [6] Mining at the site by shafts began in the 1920s.
The boron they produced was oxidized to boron oxide. [26] [27] Aluminium, like boron, was first known in minerals before it was finally extracted from alum, a common mineral in some areas of the world. Antoine Lavoisier and Humphry Davy had each separately tried to extract it. Although neither succeeded, Davy had given the metal its current name.
