Only about 0.001% of Earth's crust consists of boron. The two main producers of commercial boron are the USA and Turkey, with Turkey having about 72% of teh known commercially viable deposits. Due to its reactivity boron is not found in elemental form, but is commercially extracted from a number of compounds including borax and boric acid.

Boron has a large number of commercial uses. Its low thermal expansion makes it an essential element in heat-resistant glass, such as Pyrex. Boron fibres are used in high-strength composites for the aerospace industry and in high-end golf clubs and fishing rods. A number of boron compounds are extremely hard, and these are used in abrasives and machine tool bits. Boron is also an essential component of [[Neodymium]] (rare earth metal) magnets, which are used in high quality loudspeakers and many other applications.
