Silicon Metal: A Versatile Material with Wide-Ranging Applications

Silicon metal is a versatile material with a wide range of applications in various industries. It is primarily used as an alloying agent in the production of aluminum alloys, steel, and other metals. Si metal also finds applications in the chemical, electronics, and solar energy industries.

Khorshid Alyazh: A Leading Producer of Silicon Metal

Among the prominent producers of Si metal is Khorshid Alyazh, a Qazvin-based company in Iran. With state-of-the-art facilities and a dedicated team of experts, Khorshid Alyazh has established itself as a reliable supplier of high-quality Si metal globally.

Production Process

The production of silicon metal involves the reduction of silicon dioxide (SiO2) with carbon in an electric arc furnace. The process can be summarized as follows:

  • Raw Materials: Khorshid Alyazh sources high-grade silicon dioxide from reputable suppliers to ensure the purity and quality of its products.
  • Electric Arc Furnace: The silicon dioxide is charged into an electric arc furnace along with carbon electrodes.
  • Reduction: The electric arc creates an intense heat, which causes the silicon dioxide to reduce and combine with the carbon to form Si metal.
  • Tapping: Once the reduction process is complete, the molten Si metal is tapped from the furnace.
  • Refining: The tapped Si metal undergoes further refining processes to remove impurities and achieve the desired composition and properties.

Product Specifications

Khorshid Alyazh produces silicon metal in various grades to meet the diverse requirements of its customers. The typical specifications of its products include:

  • Silicon Content: 98-99.9%
  • Iron Content: <0.5%
