Product Description
Metallic silicon granules, also known as industrial silicon or crystalline silicon, are a high-purity silicon-based material widely used in high-tech fields such as metallurgy, chemical engineering, new energy, semiconductors, and photovoltaics. This product is refined from high-quality quartz sand through an advanced electric furnace smelting process and features high silicon content, low impurities, and stable physical properties. It is an indispensable key raw material in numerous industrial processes.
Silicon carbide granules, as a key foundational material, are widely applied in multiple core fields. In the metallurgical industry, they are used to manufacture high-performance alloys such as aluminum alloys and silicon steel, enhancing the strength and heat resistance of materials, and also as deoxidizers in steelmaking to improve the quality of steel. In the chemical and new energy industries, they are used for synthesizing organic silicon products (such as silicone rubber and silicone oil) and manufacturing photovoltaic polysilicon, promoting the development of the solar energy industry. In the semiconductor and electronic industries, they are used for purifying high-purity silicon and then serving as core materials for electronic components such as chips and integrated circuits. In the emerging technology industries, they are used to upgrade the anode of lithium-ion batteries (silicon-carbon materials) and to manufacture high-temperature-resistant precision devices for 3D printing. Their cross-domain applications cover traditional industries and cutting-edge technologies, and they are indispensable strategic resources for energy transition and intelligent manufacturing.
