General description

Silicon powder is a fine, gray powder. This silicon powder has been passed through a 325-mesh screen, meaning that the particles are small enough to pass through a sieve with openings that are approximately 44 thousandths of an inch in diameter. Silicon is a chemical element and is a hard, brittle, metallic-gray solid that is highly resistant to chemical attack and has a high melting point. Silicon is the second most abundant element in the Earth’s crust and is found in a variety of minerals.
We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This enabling product has been enhanced for energy efficiency. Click here for more information.

Application

Silicon can be used as anode material in lithium-ion batteries.

It can be used to fabricate Al2O3-C refractories. The silicon powder generates β-Sialon whiskers which imparts high-temperature strength, slag resistance and thermal shock resistance of the refractories.

It can be incorporated into high-densitypolyethylene (HDPE) polymer composites. The addition of silicon powder enhancesthermal stability and thermal conductivity of composites.
