Silicon Metal Powder for Industrial Chemistry Organic Silicone Production and Precision Material Processing

Lump silicon suits the furnace; powder suits the reaction. Industrial chemistry, organic silicone production and precision material processing all grind their feed because surface area, not mass, sets the pace of silicon chemistry. ZhenAn supplies silicon metal powder to these sectors from its Henan production base — milled, classified and certified so that what arrives at the plant is what the process model assumed.

• Smelted silicon metal as sole feedstock, selected before crushing
• Milling and air classification to the customer's sieve band or micron target
• Release testing for Si, Fe, Al, Ca and particle size on every batch
• Lined, sealed packaging that preserves the powder's fresh surfaces
• ISO 9001 management of the whole route from lump to loaded container

• Grade ladder for chemistry: 553 at 98.7% Si, 441 at 99.1%, 3303 at 99.37%
• Impurity windows narrow as the grade climbs: iron and aluminium fall from 0.5% to 0.3%, calcium from 0.3% to 0.03%
• Fineness brackets: a 200 mesh cut sits near 75 μm, a 325 mesh cut near 45 μm, with custom bands quotable
• Acceptance testing: chemistry and particle size measured on each lot against the order limits
• Paperwork: a COA is issued per batch and retained samples are held at the works
• Physical constants such as density and melt point are available from the lab on request

• Organic silicone production: contact mass for chlorosilane monomer synthesis
• Industrial chemistry: silanes, silicon esters and elemental-silicon routes
• Precision material processing: silicon nitride and advanced ceramic precursors
• Research-scale and pilot lines that need documented, repeatable lots
