Different Grades Of Silicon Metals

Silicon metal is a semiconducting metal with a grayish luster, also known as crystalline silicon or industrial silicon, which is mainly used as an additive in non-ferrous metal alloys. Its production is accomplished through a reduction reaction between quartz sand and coke in an electric furnace (chemical formula: SiO₂ + 2C → Si + 2CO), with a conventional purity of about 98% and a high purity of more than 99.99%.

Classification Core: Purity and Impurity Content
Silicon metal grades are classified based on the silicon content and the upper limit of impurities (iron, aluminum and calcium). In the production process, the initial 97-98% purity of silicon metal is produced by electric furnace reduction, and after melt recrystallization and acid treatment, the purity can be increased to 99.7-99.8%.

Silicon metal is often named with a combination of numbers (e.g., 553, 441), each of which corresponds to a decile percentage of impurity content.

Henan Tieyao Trading Co., Ltd. was officially established on March 11, 2021 with a registered capital of RMB 10 million. The company is located in the north of the South-to-North Water Diversion Bridge, 600 meters west of the Nanliusi Village section of National Highway 107, Yindu District, Anyang City, Henan Province. The company covers an area of 25,000 square meters and has extremely complete production facilities. Four medium-frequency electric furnaces operate efficiently, providing sufficient power for the smelting of ferroalloys; four alloy cored wire production lines cover various types of cored wire production such as silicon-calcium wire, calcium-iron wire, and pure calcium wire; a set of advanced crushing equipment to accurately control the product particle size. From production and smelting to crushing and processing, packaging and transportation, and then to after-sales service, a one-stop service system has been built. The strong production strength has laid a solid foundation for the company's market competitiveness.
