Silicon Metal is an indispensable backbone of modern industry, celebrated for its pivotal role across a multitude of sectors such as steel-making, cast iron production, and the manufacturing of aluminum components for aviation, aircraft, and automobiles. Additionally, it finds application in silicon optoelectronic devices, among many other industries, earning its nickname as the 'salt' of modern industries. Crafted from the smelting of quartz and coke within electric heating furnaces, this industrial marvel boasts a silicon content of approximately 98%. The balance of its composition is made up of trace impurities such as iron, aluminum, and calcium, adding to its versatile utility.
Silicon Metal lumps are meticulously produced through the high-temperature smelting of quartz and coke in electric heating furnaces. During this process, quartz undergoes reduction to transform into a molten silicon liquid. Once cooled, it solidifies into the substantial silicon metal lumps we recognize. These initial lumps are typically very large and require further processing.
Subsequently, these grand silicon masses are refined into smaller, more manageable lumps, achieving what we define as standard size. The refined Silicon Metal Lumps typically range from 10 to 100mm, making them perfectly suited for a variety of industrial applications.
With a captivating silver gray or dark gray hue and a striking metallic luster, Silicon Metal is renowned for its exceptional properties, including a high melting point, outstanding heat resistance, impressive resistivity, and superior oxidation resistance, making it an invaluable asset in numerous advanced industrial processes.
1) Silicon Metal is a cornerstone in the refractory material and power metallurgy industry, widely hailed for its remarkable ability to enhance heat resistance, wear resistance, and oxidation resistance, making it indispensable in demanding industrial applications.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as a fundamental raw material, pivotal for the synthesis of high-polymers of organic silicon, driving innovation and versatility in a multitude of chemical applications.
3) Industrial silicon powder undergoes sublimation to form monocrystalline silicon, a critical component in the high-tech arena. This essential raw material plays a vital role in the production of integrated circuits and electronic elements, propelling advancements in technology and electronics.
4) Within the metallurgy and foundry sectors, industrial silicon powder is esteemed as an iron base alloy additive. It acts as a key alloying agent for silicon steel, significantly enhancing the hardenability of steel, thereby improving performance and resilience.
5) Silicon metal is instrumental in the production of high-temperature materials, demonstrating its versatility and significance in applications that demand exceptional thermal stability and durability.
