Metallurgical Grade Silicon Metal
Products Description
Metallurgical Grade Silicon Metal (also known as industrial silicon or crystalline silicon) is the core product of industrial silicon smelting. It is produced by using quartz sand and carbonaceous reducing agents as raw materials and through high-temperature reduction in a blast furnace. The main component silicon content is ≥ 98.5%, and it is a key basic raw material in fields such as metallurgy, chemical industry, and new energy.

Various forms of metallic silicon
Lump Silicon Metal
Features: Stable purity, controllable impurities, easy for storage, transportation and feeding. It is the basic form of metallurgical grade silicon metal and is widely used in bulk purchases for aluminum alloys and organic silicon industries.
01
Granular Silicon Metal
Features: Granularity can be controlled (commonly 10-50mm), the material is applied more evenly, the reaction efficiency is higher, it is suitable for automated production lines, and is mainly used in aluminum alloy melting and precision casting fields.
02
Fine Granular Silicon Metal
Characteristics: High specific surface area and high reactivity. It is mainly used in scenarios where a large contact area is required, such as in refractory materials, metallurgical powders, and chemical synthesis.
03
Silicon Metal Powder
Characteristics: High purity, fine particle size (commonly 200 mesh and 325 mesh). It is the core raw material for refractory materials, ceramics, coatings, and metallurgical powders, and can also be used in 3D printed metal-based materials.
