What is
Microsilica
Microsilica or Silica Fume, which it is made from the oxidized
silicon vapor of silicon iron or element
silicon with special dust catcher and final turn out amorphous SiO2
powder.
Average particle size of Microsilica is around 0.*5~0.*0μm,
specific area is ****0~****0m 2 /kg, and they are with
Strong surface activity.
The main element of Microsilica is amorphous SiO2. Besides, the
burner gas accompanies impurity. Like dissociate
C, Fe2O3ã€CaOã€K2Oã€Na2O and etc. The Microsilica Color along
with the higher content of Cã€Fe2O3, the deeper
color is changed from White-Grey White-Grey-Deep Grey.
By directly collected Microsilica from burner is named Original
Micro silica. The bulk density is around **0~**0kg/m3.
But for the convenience transportation and application, the
Original Microsilica can be increased bulk density.
