Introduction: Microsilica is ferroalloy smelting ferrosilicon and industrial silicon(silicon metal)ore heat furnace to produce a large number of volatile strong SiO2 and Si gas, gas emission and air oxidation quickly after condensation precipitation. It is a big industrial by-product of smelting, the whole process need to recycle with dust environmental protection equipment, because the density is small, still need to use encryption device is encrypted.

Main Features:
1. Cement or concrete admixture: micro silicon powder is able to fill cement intergranular pore, at the same time and the hydration products generate gels, magnesium oxide reaction to generate gel with alkaline materials.
2. Refractory additives: high quality micro silicon powder is mainly used for high performance refractory castable, bricks, ladle material, air brick, gravity type refractory pouring injection materials and dry and wet method.
3. Metallurgy pellet binder: micro silicon powder mixed with water after making pellet sintering, natural drying or not plus binder, pellets in very few impurities, can return to electric furnace smelting as materials.

Shipping: Shipped in 30 days after payment.

Packaging: The product use fumo plastic woven bag packing. Packaging specifications for: 30 kg/bag, 25 kg/bag, 50 kg/bag .
1.Waterproof packaging
2. OEM 
3. Printing
