Silicon Metal is a pivotal industrial product, serving a multitude of vital roles across various sectors. Its applications span from steel-making and cast iron to the production of aluminum components for aviation, aircraft, and automotive parts. Moreover, it is indispensable in the silicon optoelectronic device industry and numerous other fields. Appropriately dubbed the 'salt' of modern industries, Metal Silicon is crafted through the smelting of quartz and coke in an electric heating furnace. Its primary composition is approximately 98% silicon, with the remaining impurities comprising iron, aluminum, calcium, and others.
Silicon Metal lumps are meticulously produced in an electric heating furnace using quartz and coke. During this process, quartz undergoes a redox reaction, transforming into molten silicon liquid. As it cools, this liquid solidifies into the large primal silicon metal lumps we recognize. These initial lumps, substantial in size, are then processed further.
They are refined into smaller, standard-sized lumps, known as Silicon Metal Lumps, ranging from 10-100mm in size, perfect for various industrial applications.
These Silicon Metal Lumps possess a captivating silver gray or dark gray hue with a striking metallic luster. They are renowned for their high melting point, excellent heat resistance, commendable resistivity, and outstanding oxidation resistance, making them a material of choice for demanding applications.
1) Silicon Metal finds its broad utility in the realm of refractory materials and power metallurgy. It is instrumental in enhancing properties such as heat resistance, wear resistance, and oxidation resistance, making it indispensable in these industries.
2) Within the chemical domain of organic silicon, industrial silicon powder serves as the foundational raw material. It plays a pivotal role in the creation of high polymers of organic silicon, highlighting its critical importance in the industry.
3) Industrial silicon powder undergoes a transformation into monocrystalline silicon, a key component in high-tech sectors. It is an essential raw material used extensively in the fabrication of integrated circuits and electronic components, underlining its significance in advanced technology fields.
4) In the fields of metallurgy and foundry, industrial silicon powder is esteemed as an additive to iron-based alloys and as an alloying agent in silicon steel. This enhances the hardenability of steel, showcasing its value in improving metallurgical processes.
5) Silicon metal is crucial in the manufacturing of high-temperature materials, offering significant benefits in applications requiring durability and resistance to extreme conditions.
