Trend of boron

The average cost of crystalline elemental Boron is US$5/g. Elemental Boron is chiefly used in making boron fibres, which are deposited by chemical vapour deposition on a tungsten core (see below). Boron fibres are used in lightweight composite applications, such as high-strength tapes. This use is a tiny fraction of total boron use. Boron is introduced into semiconductors as boron compounds by ion implantation. The estimated global consumption of Boron (almost entirely as boron compounds) was about 4 million tonnes of B2O3 in 2012. As for compounds such as borax and kernite, they cost US$377/tonne in 2019. Boron mining and refining capacities are considered adequate to meet expected levels of growth through the next decade. The form in which Boron is consumed has changed in recent years. The use of ores like colemanite has declined following concerns over arsenic content. Consumers have moved toward using refined borates and boric acid with a lower pollutant content. Increasing demand for boric acid has led several producers to invest in additional capacity. Turkey's state-owned Eti Mine Works opened a new boric acid plant with a production capacity of 100,000 tonnes per year at Emet in 2003. Rio Tinto Group increased the power of its boron plant from 260,000 tonnes per year in 2003 to 310,000 tonnes per year by May 2005, with plans to grow this to 366,000 tonnes per year in 2006. Chinese boron producers have been unable to meet the rapidly increasing demand for high-quality borates. This has led to sodium tetraborate (borax) growing by a hundredfold between 2000 and 2005 and boric acid imports rising by 28% per year over the same period.
