Fine Mesh Silicon Powder 50–500 Mesh Material

Silicon metal powder is processed by crushing and sieving bulk silicon metal into fine granular powder, widely applied as a deoxidizer and alloying ingredient in steelmaking, casting and metallurgical alloy production.

It features a larger specific surface area and superior dispersion compared with silicon lumps, enabling more even silicon distribution and faster chemical reactions in production, ideal for processes not suitable for direct lump feeding.

We provide silicon powder in 50–500 mesh with customizable particle grades. Coarser mesh types are convenient for weighing, feeding and storage; finer mesh delivers better mixing performance and dispersion effect.

Improper particle size will bring production troubles: overly coarse powder causes uneven mixing and component segregation; excessively fine powder leads to dust generation, moisture absorption and caking, resulting in material loss, unstable batching and extra cleaning work.

We can tailor silicon powder specifications per your demands. You only need to confirm the required mesh size, silicon purity, impurity standards and packaging. We will verify chemical composition, mesh range and provide COA and packing details before delivery, and offer sealed packaging for fine powder to avoid moisture and dust issues.

Silicon Powder Warehouse and Packing Area

Export Packing and Loading Support

One customer used silicon powder in an industrial mixing process. Their previous material had uneven particle size, and some batches contained more coarse particles than expected. During production, the powder did not mix evenly with other raw materials, so their operators had to do extra screening before use.

They also had problems with fine powder dust and slight clumping after storage. This made daily feeding less convenient and increased cleaning work around the mixing area.

After checking their required mesh range, moisture limit and packing method, we recommended silicon powder within the 50–500 mesh range. For their process, we confirmed the particle size, Si content, impurity limits and moisture level before shipment. We also used moisture-resistant packing to reduce storage problems during transport.

After receiving the material, their team reduced extra screening work, and the powder was easier to use in daily mixing. The confirmed mesh range also helped them keep material preparation more stable from batch to batch.

If your current silicon powder has issues such as uneven particle size, too much dust, clumping after storage, or repeated screening before use, you can send us your material standard and application details. We can help you check whether a different mesh range, packing method or moisture control option is more suitable for your production.

Q: What mesh sizes can you supply for fine silicon powder?
A: We can supply silicon powder within the 50–500 mesh range. Specific mesh sizes can be discussed according to your application and order quantity.

Q: How should I choose between coarse and fine mesh?
A: Coarser mesh is usually easier to feed and handle. Finer mesh gives better dispersion and larger contact surface, but it may need better dust and moisture control.

Q: Can you customize the mesh size?
A: Yes. If you have a target particle size or mesh distribution, please send it before quotation. We will check stock or processing options.

Q: Can you provide COA before shipment?
A: Yes. We can provide COA before loading. If you need to check Si, Fe, Al, Ca, C, moisture or particle size, please send your requirement before quotation.

Q: How do you pack 500 mesh fine silicon powder?
A: For finer powder, PE-lined bags, sealed packing, drums or pallet packing can be discussed to reduce moisture and handling problems.

Q: Can I get a sample first?
A: Sample can be discussed according to mesh size and stock. Please tell us the mesh, quantity and application you want to test.

Q: What information should I send for quotation?
A: Please send required mesh size, Si content, impurity limits, moisture requirement, order quantity, packing method, destination port and application.
