Microsilica, also known as Silicafume, is a byproduct of production of silicon and ferrosilicon alloys. Because of its extreme fineness and high silica content, silica fume is a highly effective pozzolanic material.
SiO2:    85 to 97 %

Density: 100 to 650   kg/ m3 
         (Densified Silica Fume and UnDensified Silica Fume)

Packing: Jumbo bags of 900kg/bag (20 bags per 20 FCL)
         or 20kg or 25kg small plastic woven bags.

Payment: T/T or L/C at sight
         (or CAD or D/P at sight with 30% deposit before shipmt ).

Delivery: We have warehouse in Guangzhou, Shanghai, Tianjin has stocks.
          so that we can load goods into container once we receipt the payment.
