Key Properties of silicon metal powder
Chemical Composition: Primarily silicon (≥98%), with traces of Fe, Al, Ca, etc.
Appearance: Gray-black powder with a metallic luster.
High Reactivity: Combines readily with oxygen and halogens.
Thermal Stability: Melting point ~1,414°C, boiling point ~3,265°C.
Electrical Properties: Semiconducting behavior (varies with purity).
Applications of silicon metal powder
Chemical Industry: Raw material for silicones, silanes, and silicon-based compounds.
Metallurgy: Alloying agent in aluminum, steel, and cast iron production.
Electronics: Used in photovoltaic (solar) cells and semiconductor devices (higher purity grades).
Refractories: Additive for high-temperature materials.
Energy: Anode material in lithium-ion batteries.
Advantages of silicon metal powder
Enhances strength and corrosion resistance in alloys.
Improves performance in electronic applications due to its semiconductor properties.
Cost-effective compared to ultra-high-purity silicon (e.g., polysilicon for solar panels).
Particle Sizes & Grades
Available in various mesh sizes (e.g., 100 mesh, 200 mesh, 325 mesh) and purity levels (98%, 99%, 99.9%) for tailored applications.
