China Drives Demand Growth of Boron     

Global demand for boron grew strongly in the three years to 2008, according to Roskill Information Services Ltd. Products containing boron in the form of borates or boric acid pervade every part of everyday life from borosilicate glass in LCD screens to composites used in car body panels to glass wool for loft insulation.
   Growth has been driven by an expansion of demand from China, where consumption rose by 15% per annual from 2000 to 2008, Roskill Information Services said in its 243-page report. The increase in market share held by Asian countries reflects the shift in production of textile-grade fibreglass, borosilicate glass and ceramics away from North America and Europe to countries with lower production costs.
   Following the years of strong growth, 2009 saw a sharp drop in demand for borates, but, in the second half of the year, markets for both textile-grade fibreglass and borosilicate glass recovered and demand for borosilicate glass in LCD screens is expected to grow by 15% in 2010. The main factors affecting future demand for textile-grade fibreglass are continued growth in electronic products, increased penetration of fibreglass in markets traditionally held by steel and concrete and the emergence of new markets such as turbine blades for wind power generation.
   An up-turn in construction activity and the increase in government-led initiatives to reduce energy consumption will provide a recovering market for insulation-grade fiberglass in the medium term, Roskill Information Services projected.
   World production of natural and refined borates remains highly concentrated in Turkey and the USA, with Rio Tinto Minerals and Eti Mine accounting for around 75% of supply. The high B2O3 content (>26%) of the colemanite, tincal and kernite mined in Turkey and California is the main factor contributing to the leading position of these two companies in world borates supply.
   The gap between China's domestic production and demand (and the relatively low-grade of locally mined borates) has been, and will continue to be, the main factor driving capacity expansions worldwide. Since 2003, expansions undertaken by Rio Tinto Minerals in the USA, Quiborax in Chile, Eti Mine in Turkey and Manufacturas Los Andes in Argentina, have raised boric acid capacity by over 200 000 t/a and were mainly aimed at the Chinese market.
    Future expansion is dominated by plans to expand capacity for refined borates, boron oxide and calcined tincal in Turkey. Other projects under consideration are to increase boric acid production in Argentina and Bolivia and to exploit brine deposits in Tibet and Qinghai of China.
