The Necessity Of Producing Silicon For The Chemical Industry

China's production of metal silicon (silicon content is mainly 98.5%), the original is mainly metallurgical silicon, chemical silicon metal (silicon content is mainly 99.85%) production has been developed since the mid-1990s, China's chemical silicon production and export volume growth. From 1999 to 2001, China's exports of chemical silicon to Japan have reached 22,000 tons, 30,000 tons, 40,000 tons, and China's exports of chemical silicon to Japan in 2001 have accounted for more than 40% of Japan's chemical silicon imports.

Chemical silicon refers to metallic silicon used in the production of organosilicon and polysilicon. From a worldwide perspective, the consumption of metallurgical silicon is more than the consumption of chemical silicon, but with the continuous development of science and technology, chemical silicon is used in silicone and semiconductor production and other fields continue to expand, widely used in the production of silicone monomer and polymer silicone oil, silicone rubber, silicone resin building corrosion protection, waterproof agent, etc. They have high temperature resistance, electrical insulation, radiation resistance, waterproof and other unique properties. Used in electrical, aviation, machinery, chemical, medicine, national defense, construction and other departments.

Chemical silicon is widely used as a high-tech field and an important basic industry, and its consumption tends to grow steadily. Under normal circumstances in the international market, the price per ton of chemical silicon is 300-400 US dollars higher than that of metallurgical silicon. Therefore, whether from meeting the export and domestic demand, or from improving the economic efficiency of metal silicon enterprises, improve product quality, and vigorously develop chemical silicon production is necessary.
