Silicon Metal Powder 200 Mesh & 325 Mesh for Organic Silicone Production and Chemical Processing
ZhenAn supplies metallurgical-grade silicon metal powder in two classified sieve cuts — 200 mesh and 325 mesh — engineered as the starting feedstock for organic silicone synthesis and broader silicon-based chemical processing. Each lot is milled on a closed circuit and released with a certificate of analysis covering silicon content, Fe/Al/Ca impurities and sieve residue.
What Is Silicon Metal Powder for Organic Silicone Production and Chemical Processing?
Silicon metal powder is elemental silicon, ground and classified from metallurgical-grade lumps. In organic silicone production it serves as the starting feedstock: the powder reacts with methyl chloride over a catalyst to form chlorosilane monomers — the building block of nearly every silicone oil, rubber and resin on the market. ZhenAn supplies this chemistry in two sieve cuts, 200 mesh and 325 mesh, so each plant can match powder fineness to its reactor design, fluidization quality and conversion targets.

Chemistry follows the silicon metal grade table published on this site. Grade 441 (Si 99.1%, Fe ≤0.4%, Al ≤0.4%, Ca ≤0.1%) and grade 3303 (Si 99.37%, Fe ≤0.3%, Al ≤0.3%, Ca ≤0.03%) are the usual picks for silicone duty.
Applications in Organic Silicone and Chemical Processing
- Direct synthesis of methylchlorosilane monomers in fluidized-bed reactors
- Downstream silicone intermediates such as linear and cyclic siloxanes
- Silicone oil, rubber, resin and silane coupling agent production
- Any silicon-based chemical synthesis that requires an elemental Si source

Frequently Asked Questions from Silicone Producers
Which cut suits a fluidized-bed direct process?
Finer 325 mesh exposes more surface per gram, which supports conversion; confirm against your reactor design.
Which grade do most silicone plants order?
Grade 441 is the common workhorse; 3303 is chosen when tighter impurity ceilings pay for themselves.
How is the powder packed?
25 kg bags with an inner liner, or 1 MT jumbo bags.
What documents arrive with a lot?
A batch COA listing Si, Fe, Al, Ca and sieve residue.
Can ZhenAn hold a custom sieve residue?
Yes — send the pass rate or PSD limits and the mill works to them.
What is the shipping window?
5–10 working days from cleared payment.
