silica fume manufacturer, gansu xinyuan micro silicon powder co., ltd., introduce you to micro silicon powder physical properties and the composition, micro silicon powder is also called the silicon ash or condensed silica fume, ferroalloy smelting ferrosilicon and industrial silicon, silicon metal, ore heat furnace to produce a large number of volatile strong sio2 and si gas, gas emissions and air oxidation quickly after condensation precipitation. it is a by-product of large-scale industrial smelting, and the whole process needs to be recycled with dusting environmental protection equipment, because the density is small and also needs to be encrypted with encryption equipment.

1. physical properties of silicon powder:

... '> present form: microsilicon powder is an amorphous superfine (amorphous) powder

typical color: brown (naturally white, with increasing density, gradually deepened in silicon powder)

characteristic size of iamm: 0.5mm (particle size: 100 ~ 1000nm, > 90% of < < l < m)

the specific surface area is 15 ~ 27 m2/g

loose bulk density: 150 ~ 200 kg/m3

. activity index: 90%--110%

water requirement ratio from 125 to 135%

2. the main chemical composition of microsilica powder is sio2, with content up to 85-95%. its elements include fe2o3, al2o3, cao, k2o, na2o, mgo, c, etc.
