Description

Other Notes

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.

Application
Silicon can be used as anode material in lithium-ion batteries. It can be used to fabricate Al2O3-C refractories.
