Silicon Metal is an indispensable industrial masterpiece, a cornerstone in the realms of steel-making, cast iron, and aluminum industries, including the dynamic spheres of aviation, aircraft, and automobile components. Its versatility extends to the burgeoning field of silicon optoelectronic devices, solidifying its status as the "salt" of modern industries. Originating from the fusion of quartz and coke within an electrically heated furnace, this marvel of metallurgy boasts a silicon content of approximately 98%, with impurities such as iron, aluminum, and calcium making up the remainder.
The production of Silicon Metal lumps involves the transformation within an electric furnace. Quartz and coke undergo a remarkable redox reaction, culminating in the formation of molten silicon liquid. Upon cooling, this liquid crystallizes into solid form, resulting in the substantial primary silicon metal lump.
These formidable lumps are subsequently refined into more manageable sizes, commonly referred to as standard sizes. The dimensions of Silicon Metal Lumps range between 10-100mm.
Boasting a striking silver or dark gray hue with a captivating metallic sheen, Silicon Metal is renowned for its high melting point, exceptional heat resistance, impressive resistivity, and unparalleled oxidation resistance, making it a vital asset in industrial applications.
1) Silicon Metal finds its universal significance in the refractory material and power metallurgy industries. It is renowned for enhancing heat resistance, wear resistance, and oxidation resistance, making it indispensable in these fields.
2) Within the realm of organic silicon chemistry, industrial silicon powder serves as the fundamental raw material for crafting high polymers of organic silicon. It is the cornerstone of innovative chemical processes.
3) When sublimated into monocrystalline silicon, industrial silicon powder becomes a pivotal component in the high-tech sector. It is a vital raw material for crafting integrated circuits and electronic elements, driving technological advancements.
4) In the realms of metallurgy and foundry, industrial silicon powder plays a crucial role as an additive in iron-based alloys and as a component in silicon steel alloy pharmaceuticals. This contribution significantly enhances the hardenability of steel.
5) Silicon metal is integral in the manufacture of high-temperature materials, offering reliability and durability under extreme conditions.
