company news about What is metallurgical silicon used for?

Metallurgical silicon, also known as metallurgical-grade silicon (MG-Si), is a refined form of silicon (typically around 98–99% pure) produced by reducing quartz with carbon in an electric arc furnace. It is not pure enough for electronic applications, but it serves as a critical raw material in several industries. Here are its main uses:

 1. Aluminum Alloys

• Primary use (≈60–70% of MG-Si):

• Improves strength, castability, and corrosion resistance of aluminum.

• Used in automotive parts, aircraft, and construction materials.

 2. Silicone Production

• Siloxanes and Silicones:

• MG-Si is converted into chlorosilanes (e.g., trichlorosilane), which are used to produce silicones—versatile materials used in:

  • Lubricants

  • Sealants

  • Medical implants

  • Cosmetics

  • Cookware

3. Solar and Semiconductor Feedstock (via Upgrading)

• MG-Si is the starting material for producing polysilicon, which is:

  • Further refined to 99.9999%+ purity.

  • Used in solar photovoltaic cells and semiconductors.

 4. Battery Anodes (Emerging Use)

• Research and development are exploring MG-Si as a lower-cost source of silicon for Li-ion battery anodes.

• Silicon anodes can store more lithium than traditional graphite anodes.

5. Steel and Cast Iron Production

• Acts as a deoxidizer and alloying element.

• Improves strength and workability of steel and iron products.
