Industrial silicon and ferrosilicon are critical components in the manufacturing sector, serving as fundamental ingredients in a variety of metal alloys. These materials are essential in enhancing the properties of metals, contributing to the production of electronics, and improving industrial processes. With their extensive applications, they are often referred to as the "magic metals" of the industry.
Industrial silicon, also known as metallurgical silicon or simply silicon, is a high-purity product containing at least 98.5% silicon. It is a vital non-ferrous alloy additive used in the production of various metals and plays a significant role in the electronics and chemical industries. Industrial silicon is transformed through several processes to produce polysilicon, which is then mechanically cut into monocrystalline silicon for use in a wide array of electronic devices, including integrated circuits (ICs), VCDs, and DVDs.
According to a report by Grand View Research, the global silicon metal market size was valued at USD 6.05 billion in 2019 and is expected to grow at a compound annual growth rate (CAGR) of 4.6% from 2020 to 2027. This growth is attributed to the increasing demand for aluminum-silicon alloys in the automotive and construction industries.
Ferrosilicon is an iron-silicon alloy made from coke, steel scrap, and quartz, typically produced in a submerged arc furnace. It is primarily used as a deoxidizer in steelmaking, releasing heat and improving the temperature of molten steel. Ferrosilicon also serves as an alloy additive and is used in various steel grades, including low alloy structural steel, spring steel, and electrical silicon steel.
The steel industry is a major consumer of ferrosilicon, with the production of one ton of steel requiring approximately 3 to 5 kg of 75% ferrosilicon. The addition of silicon to steel can significantly improve its mechanical properties, with general steel containing 0.15%-0.35% silicon, and electrical steel containing even higher percentages.
The demand for industrial silicon and ferrosilicon is closely linked to the growth of the automotive, construction, and electronics industries. As these sectors continue to expand, the need for these materials is expected to rise. Innovations in production techniques and the development of new applications for silicon-based materials are likely to drive market growth further.
For more detailed information on the industrial silicon and ferrosilicon market, authoritative sources such as the International Ferroalloys Conference and industry reports from Grand View Research provide valuable insights.
In conclusion, industrial silicon and ferrosilicon are indispensable materials in modern manufacturing, with their applications spanning across multiple industries. Their ability to improve the properties of metals and contribute to technological advancements underscores their significance in the global market.
