Advantages of Silicon Metal
High melting point
The melting point of silicon metal is as high as 1410℃, which makes it have excellent stability in high temperature environment.
Good heat resistance
Can maintain stable performance at high temperature, not easy to deformation or melting.
High resistivity
With high resistivity, it is suitable for application scenarios requiring high resistance performance.
High oxidation resistance
It can maintain good oxidation resistance at high temperature and prolong service life.
Specification of Silicon Metal
|
Product name |
Silicon metal |
|
Appearance |
Usually lumpy, dark grey with blue tone (may vary with production process and purity). |
|
Composition |
The main component is silicon, usually silicon content ≥99.6%, and contains trace iron, aluminum, calcium and other impurities. |
|
Particle size |
The particle size range may vary from manufacturer to manufacturer and application, but is generally between 10 and 100mm. |
High purity: Typically 98-99.99% si, with impurities like iron, aluminum, and calcium.
High melting point: 1,414°c, making it heat-resistant.
Brittle and crystalline: Breaks easily into shiny, gray metallic chunks.
High conductivity: Used in semiconductors and electronics.
Different Grades Of Silicon Metal
Standard silicon metal (98-99.5% si)
Used in aluminum alloys and chemicals.
High-purity silicon (99.99%+ si)
Used in semiconductors and solar panels.
Aluminum alloys: Improves strength, corrosion resistance, and casting properties in aluminum-based products (used in automotive and aerospace industries).
Semiconductors & electronics: Ultra-pure silicon (99.9999%+ si) is used to make computer chips, solar panels, and other electronic components.
Silicones & chemicals: Used in the production of silicones, which are widely used in lubricants, sealants, and medical applications.
Solar panels: High-purity silicon is a key material in photovoltaic cells for solar energy production.
Steel & foundry: Acts as a deoxidizer and enhances the properties of steel and cast iron.
Production Process of Silicon Metal
Raw materials
Quartz (sio₂), carbon sources (coal, petroleum coke, wood chips), and sometimes iron.
Reduction process
Quartz reacts with carbon at high temperatures to form silicon metal and co₂
Refining & cooling
The molten silicon is tapped, cooled, and crushed into different sizes for various applications.
Purification
For electronics and solar applications, further purification is done to achieve ultra-high purity.
