Introduction to silicon metal

Silicon metal is a very important industrial product used in many industries such as steelmaking, cast iron, aluminum (aviation, aircraft and automotive parts production) and silicon photovoltaic devices. Known as the “salt” of modern industry.

Silicon metal is a product smelted from quartz and coke in an electric heating furnace. The main component silicon content is about 98%. The remaining impurities are iron, aluminum, calcium, etc.

The silicon metal provided by Zhen’an is processed from high-quality industrial silicon, with a complete range of varieties and three forms of block/granule/powder. Used in electronics, metallurgy, chemical industry and other industries. It is silver gray or dark gray, with metallic luster, high melting point, good heat resistance, high resistivity and excellent oxidation resistance.

Shape of silicon metal


Silicon metal block

The metal silicon block is relatively large, suitable for some industrial production processes that require a large amount of materials, and helps to reduce oxidation and loss


Silicon metal granular

Granular silicon metal has a relatively uniform particle size and shape, which is beneficial for mixing and use. Easier to react and interact with other materials.

Metal silicon powder

Metal silicon powder has a larger surface area, the contact area becomes larger, and the reaction speed is very fast. Our company can provide you with 4N metal silicon powder with a purity of up to 99.99%

Properties of silicon metal

The addition of metal silicon can significantly increase the strength of the alloy. Silicon can form a silicide phase, refine the grain structure of the alloy, and enhance the strengthening effect of the grain boundary, thereby greatly increasing the strength of the alloy.

the addition of metal silicon can improve the plasticity of the alloy. Silicon can promote the dislocation slip at the grain boundary and increase the deformability of the material, so that the alloy can better withstand deformation and is not easy to break when it is stressed.

the presence of metal silicon can significantly improve the hardness and wear resistance of the alloy. The silicide phase has high hardness and can form a hard thin layer on the surface of the alloy, thereby improving the wear resistance and scratch resistance of the alloy. Silicon can react with metal elements in the alloy to form a corrosion-resistant silicide phase, which can effectively prevent the corrosion of the alloy by the corrosive medium and prolong the service life of the alloy.

the presence of metal silicon can improve the thermal stability of the alloy. The silicide phase can maintain a relatively stable structure at high temperatures, resist thermal deformation and thermal fatigue of the alloy, and maintain the performance stability of the alloy.

metal silicon has a strong degassing ability. Silicon can react with oxygen and other gases to form gas compounds, which can effectively remove the gas in the alloy and reduce the generation of pores and defects.

The silicon metal provided by Zhen’an has a high cost performance because of the low cost of raw material acquisition, low power cost and labor cost. Choosing Zhen’an as your partner can improve your company’s benefits.

What projects can silicon metal provide services for?

For Steelmaking:

In the process of smelting steel, the addition of metal silicon can significantly improve the strength, hardness and corrosion resistance of steel. At the same time, metal silicon can also adjust the structure and metallurgical properties of steel, and reduce the thermal expansion coefficient of steel.

Metal silicon has a strong degassing effect, which can remove hydrogen and oxygen in molten steel, reduce the gas content in steel, and reduce the occurrence of pores and shrinkage cavities in steel. This helps to improve the steel’s ability to control impurities and improve the quality and performance of the steel.

Choosing the Optimal Silicon Metal for Your Steel

For Casting:

When you are casting alloys, adding metal silicon can improve the strength and plasticity of castings and improve the surface finish of castings.

Silicide has high hardness and wear resistance, and can form a hard thin layer on the surface of castings to resist wear and friction, and improve the wear resistance of castings. At the same time, metal silicon can reduce the formation of pores, increase the density and structural compactness of castings, and ensure the dimensional stability of castings.

Choosing the Best Silicon Metal for Your Casting

Used to make high-purity silicon:

High-purity silicon material is an important inorganic non-metallic material with a wide range of applications, including electronics, optics, solar photovoltaics, integrated circuit manufacturing, etc.

Metal silicon can be prepared into high-purity silicon material through a series of refining and refining processes. Through smelting, degassing, refining and other processes, impurities and non-metallic elements in metal silicon can be effectively removed, thereby obtaining high-purity silicon materials.

The purity of high-purity silicon materials can reach more than 99.9999%, meeting the stringent standards for purity requirements in the fields of electronics and optics.
