Anyang Hongshun Industrial Co., Ltd.

Silicon metal (industrial silicon) is the "salt" of modern industry, a crucial industrial raw material smelted in a submerged arc furnace using silica and a carbonaceous reducing agent. Primarily composed of silicon, it contains impurities such as iron, aluminum, and calcium. It is widely used as an additive in non-ferrous metal alloys, in steelmaking, and in the aluminum industry (for aviation and automotive parts manufacturing). Purified industrial silicon can be made into polycrystalline and monocrystalline silicon for use in the photovoltaic and electronics industries. Silicon metal product forms include: Silicon metal chunks: 10-100mm standard particle size; Silicon metal powder: 100 mesh, 200 mesh, and 325 mesh specifications. Silicon metal is classified based on the content of the three main impurities: iron, aluminum, and calcium. Standard grades include 553, 551, and 441; high-purity grades include 3303 and 2502; and special grades include 1101. Silicon Metal Production Process: Raw Material Preparation: Silica (SiO₂ ≥ 95%) and Low-Ash Coke; Submerged Arc Furnace Smelting: High-Temperature Reduction at 1900°C; Refining and Purification: Pickling to Remove Impurities; Crushing and Classification: Producing into Blocks or Powders; Chemical Reaction: SiO₂ + 2C → Si + 2CO↑; Main Applications of Silicon Metal: Aluminum Alloys: Improving Alloy Fluidity, Reducing Thermal Cracking, and Improving Air Tightness; Silicones: Silicon Rubber, Silicon Resin, and Silicon Oil; Semiconductors: Polycrystalline Silicon, Monocrystalline Silicon, and Photovoltaic Materials; Silicon Alloy Products: Silicon Metal can be alloyed with various metals to enhance performance: Silicon-Aluminum Alloys: Used in Motor Housings and Brackets; Silicon-Copper Alloys: Improving Electrical and Thermal Conductivity; Silicon-Manganese Alloys: A Deoxidizer for Steelmaking; Silicon Metal Market Analysis: Global industrial silicon production capacity is expected to reach approximately 7.783 million tons in 2025, with China accounting for 81.05%. Major producing countries include China, Brazil, the United States, and Norway.
