Physical state: fesi75 series fesi pouring thickness, each brand shall not exceed 100 mm silicon ingots;
Fesi65 spindle shall not exceed 80 mm.

Silicon segregation of not more than 4%.
Large particle: 50-350mm size: 20 -, 200mm, small size: 10 ~ 100mm, minimum size: 10-50 small size, of which 90% above.
Packing: according to buyer's request, fesi can be used in the container, bulk, form of shipment.
Using bags or containers packaging, packaging outside should be clearly marked.

Ferrosilicon smelting: ferrosilicon is coke, steel scurf, quartz (or silica) as raw material and using made of electric smelting. Refining ferrosilicon, is from the silex silicon in containing sio2 out. Reduction Smelting ferrosilicon mostly used metallurgy as reductant.

Packing following special requirement.
