Metal Silicon For Metallurgical Industry

The metal silicon produced in China (silicon content is mainly 98.5%) was originally mainly metallurgical silicon. The production of chemical silicon metal (silicon content is mainly 99.85%) has mainly developed since the mid-1990s. my country's chemical silicon The output and export volume grew rapidly. From 1999 to 2001, my country's chemical silicon exports to Japan have reached 22,000 tons, 30,000 tons, and 40,000 tons respectively. In 2001, my country's chemical silicon exports to Japan accounted for more than 40% of Japan's chemical silicon imports. . China has begun to join the ranks of chemical silicon producers and suppliers, and the number of companies producing chemical silicon is increasing. Since Shanghai Guangji Silicon Materials Co., Ltd. fully disclosed the carbothermal reduction smelting process in 2002, China's silicon metal production capacity rapidly increased from 100,000 tons per year to 1.2 million tons between 2002 and 2004.
