Silicon Metal, also known as industrial silicon, is a grey or dark grey non-ferrous metal with a metallic luster. It's typically produced by smelting quartz and carbonaceous reducing agents in an electric arc furnace.
Product Features:
-
High Purity: Strict control of impurities like Iron, Aluminum, and Calcium.
-
High Silicon Content: Typically ranges from 98.5% to 99.99%.
-
Excellent Electrical & Thermal Conductivity: Ideal for electronic and thermal management.
-
High Temperature & Oxidation Resistance: Enhances material durability.
Product Classification & Grades:
Silicon metal is strictly classified by the content of its three key impurity elements: Iron (Fe), Aluminum (Al), and Calcium (Ca). We offer internationally recognized standard grades, including but not limited to:
-
Common Grades: 553, 441, 421, 3303, 2202, etc.
-
High Purity Grades: Such as 2502, 1101, for semiconductor and photovoltaic applications.
Customized grades are available upon client request.
Primary Applications:
-
Aluminum Alloy Industry: An alloying element improving casting strength and performance (automotive, aerospace).
-
Organosilicon Industry: Fundamental raw material for silicone rubber, silicone oil, etc. (construction, electronics, medical).
-
Photovoltaic & Semiconductor: Core material for solar cells, chips, and integrated circuits.
-
Refractory Materials: Used as an antioxidant or additive to enhance refractory performance.
