Product Description Product Description:Micro silica ,also called silica fume or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces.The raw materials are quartz,coal and woodchips.The smoke that results from furnace operation is collected and sold as silica fume, silica fume consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2),its average granule diameter is 0.15~0.20um,specific surface area is 15000~20000m2/kg,and it has extremely strong surface active.Application1) Cementitous Repair Products (Mortars & Grouts)? Low permeability, increase resistance from chlorides, acids, nitrates and sulfate etc2) Oil Well Grouting? Increase durability and compressive strength, decrease permeability, better control of gas leakage3) Concrete Tile, roofing & wallboard,panels? Lightweight and improve the strength4) other application, such as waterglass industry, thermal insulation material etc.PACKING:1.Packing: Net 25kg PP bag or 550kg Jumbo bag2.Delivery time:3-7 working days after deposit3.We have full stock and can deliver within short time.
