Silicon Metal Granules
Representative Grade: 553#
Representative Grade: 441#
Representative Grade: 3303#
introduction
Silicon Metal Granules are small-sized particles of high-purity silicon produced from metallurgical-grade silicon. With uniform particle size and high reactivity, they are widely used in aluminum alloying, chemical processing, and semiconductor or photovoltaic applications requiring fast melting and precise dosing.
features
Controlled Particle Size
Processed into uniform granules (typically mm-level), enabling precise dosing and improved process control in industrial applications.
Efficient Reactivity
Granular form provides higher surface area than lumps, supporting faster melting and more uniform reaction.
Consistent Quality
Produced via high-temperature electric arc furnace refining (>1800°C), ensuring impurity separation and batch-to-batch consistency.
Flexible Processing Forms
Can be supplied as granules or further processed into powders (30–425 mesh) to match different downstream process requirements.
