Preparation
In the industry, silicon metal is typically produced by reducing silicon dioxide using carbon in an electric furnace. The chemical reaction equation is SiO2 + 2C → Si + 2CO. The purity of the silicon produced in this manner is 97 to 98%, which is referred to as metallic silicon. After undergoing the processes of melting and recrystallizing, acid is employed to remove the impurities, resulting in metallic silicon with a purity ranging from 99.7 to 99.8%.
This production method involves several key steps and requires precise control to ensure the quality and purity of the final product. The use of an electric furnace provides a controlled environment for the reduction reaction to occur. The removal of impurities through acid treatment is a crucial step in achieving the desired high purity level.
The resulting metallic silicon finds wide application in various industries due to its unique properties and characteristics. Its high purity makes it suitable for specific applications that demand superior quality and performance.
Overall, this process demonstrates the importance of advanced techniques and strict quality control in the production of high-purity metallic silicon for diverse industrial needs.
