Necessity of producing silicon in chemical industry

Weden Metal Co.,Limited | Updated: Apr 21, 2017

China's production of metal silicon (silicon content is mainly 98.5%), originally mainly metallurgical silicon, chemical metal silicon (silicon content is mainly 99.85%) production has been developed since the mid-90, China's chemical silicon production and export volume growth faster. 1999-2001 China's exports to Japan's chemical silicon has reached 22,000 tons, 30,000 tons, 40,000 tons, 2001 China's exports to Japan's chemical silicon has accounted for the Japanese chemical silicon imports of more than 40%%. China has begun to join the ranks of chemical silicon production and supplier countries, and companies that produce silicon in chemical use are increasing. Because of Shanghai Guang-ji SI Materials Co., Ltd. in 2002 a comprehensive disclosure of carbon-thermal reduction smelting process, resulting in China between 2002 and 2004, Metal silicon production capacity rapidly from an annual output of 100,000 tons, rose to 1.2 million tons. The result was a comprehensive sanction of the NDRC, and 2006, the actual production of silicon metal fell back to 700,000 tons. Total 2006, only Shanghai Guang-ji SI material Co., Ltd. DAWU silicon factory in Xinjiang, the construction of a successful 10,000 tons of metal silicon factory crystal Xin factory. Other new silicon factory. Chemical silicon is used for the production of silicone and polycrystalline silicon metal. Worldwide, the consumption of silicon in metallurgy is more than that of chemical silicon. But with the continuous development of science and technology, the chemical silicon used in organic silicon and semiconductor production and other fields, widely used in the production of silicone monomer and polymer silicone oil, silicone rubber, silicone resin building anti-corrosion, waterproof agent, they have high temperature resistance, electrical insulation, radiation resistance, waterproof and other unique performance. For electrical, aviation, machinery, chemical, medicine, defense, construction and other departments. As the core of IC electronic components, more than 95%% is made of semiconductor silicon, semiconductor is the backbone of contemporary information industry. The fiber optic cables in a large number of applications in the "information superhighway" are also manufactured in metallic silicon. U.S. and European Union consumption of silicon has accounted for more than half of total metal silicon consumption. As the high-tech field and the important basic industry, the chemical silicon is widely used, and its consumption tends to grow steadily. In the international market normally, silicon per ton of chemical use is more than 300-400 billion dollars for metallurgical silicon price. Therefore, whether from the satisfaction of export and domestic demand, or from improving the economic efficiency of silicon metal enterprises, improve product quality, and vigorously develop chemical silicon production is necessary.
