Silicon Metal is an indispensable industrial marvel, utilized extensively in steel-making, cast iron, aluminum production (aviation, aircraft & automobile parts), and silicon optoelectronic devices, among many other industries. Often referred to as the 'salt' of modern industries, Silicon Metal is crafted from quartz and coke in an electric heating furnace. The primary composition includes about 98% silicon, with minor impurities such as iron, aluminum, and calcium.
Silicon Metal lumps are produced in an electric heating furnace using quartz and coke. Quartz undergoes a reduction-oxidation process, transforming into molten silicon. Upon cooling, it solidifies into large silicon metal lumps.
These large lumps are then processed into smaller, standardized sizes, ranging from 10-100mm in silicon metal lumps.
With a shimmering silver-gray or dark gray metallic luster, Silicon Metal boasts a high melting point, exceptional heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively used in refractory materials and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the field of organic silicone chemistry, industrial silicon powder serves as a fundamental raw material for synthesizing high polymers of organic silicon.
3) Industrial silicon powder is sublimated into monocrystalline silicon, widely adopted in high-tech sectors as a crucial raw material for integrated circuits and electronic components.
4) In metallurgy and foundry applications, industrial silicon powder acts as an additive for iron-based alloys and a pharmaceutical agent for silicon steel, enhancing steel's hardenability.
5) Silicon metal is vital in the production of high-temperature materials.
Our primary products include ferromanganese, metallic silicon, silicon carbon alloy, cored wire, ferrochrome, silicon manganese alloy, silicon carbide, ferrosilicon, silicon aluminum barium calcium, silicon barium calcium, and more. We also export refractory materials and other metallurgical products, and offer custom processing to meet specific customer requirements.
Our company operates a 206 cubic meter blast furnace, two 12,500 kVA submerged arc furnaces, two 3,600 kVA refining furnaces, four medium frequency electric furnaces, and three cladding line production lines. This setup allows us to execute manganese series hot charging and hot mixing processes, achieving high-quality, high-yield, and low-consumption production through a streamlined one-stop process.
