Silicon Metal is a quintessential cornerstone of modern industry, offering indispensable applications across a spectrum of sectors. Renowned as the "salt" of contemporary industries, it plays a crucial role in steel-making, cast iron, and aluminum production, especially in aviation, aircraft, and automobile manufacturing. Additionally, it is vital for silicon optoelectronic devices and much more. This remarkable metal is meticulously crafted from quartz and coke within the intense heat of an electric furnace, boasting a silicon content of approximately 98%. The remaining constituents are trace impurities of iron, aluminum, and calcium, underscoring its purity and industrial value.
Silicon Metal lumps begin their journey in the electric furnace, where quartz and coke undergo a dramatic transformation. Through a process of redox, quartz becomes a molten silicon liquid, which upon cooling, solidifies into the substantial primal silicon metal lumps initially formed.
These large primal lumps are precisely engineered into smaller, more manageable sizes known as standard size lumps, ranging from 10 to 100mm.
The Silicon Metal lumps exhibit a striking silver gray or dark gray hue, complete with a metallic luster. They are distinguished by their high melting point, impressive heat resistance, elevated resistivity, and superior oxidation resistance, making them an essential material in numerous demanding applications.
1) Widely treasured for its remarkable properties, Silicon Metal is extensively utilized in the refractory material and power metallurgy industry. Its use significantly enhances heat resistance, wear resistance, and oxidation resistance, resulting in superior performance of materials exposed to extreme conditions.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as the fundamental raw material crucial for the formation of high polymers in organic silicon compounds. This essential component drives innovation and functionality in various chemical applications.
3) Industrial silicon powder is transformed through sublimation into monocrystalline silicon, a critical element in the high-tech sector. This process produces a vital raw material indispensable for the development of integrated circuits and numerous electronic elements, underscoring its pivotal role in technology advancements.
4) Within the metallurgy and foundry sectors, industrial silicon powder is esteemed as an iron-based alloy additive and as a silicon steel alloying agent. Its incorporation is instrumental in enhancing the hardenability of steel, thereby optimizing metallurgical processes and improving end product quality.
5) Silicon metal plays a crucial role in the manufacture of high-temperature materials, meeting the demands of industries that require components capable of withstanding extreme conditions. Its application ensures durability and reliability in challenging environments.
