Microsilica or Silica Fume, is amorphism dusty Silicon Dioxide. When melting the Ferrosilicon Or the industrial Silicon, the Silicon steam is expelled from the flue and is oxidized and become Silicon Dioxide then it is collected by special equipment. The average size of Microsilica is Between 0.1-015μm, which is smaller than 1% of cement’s radius. Its B.E.T Fineness is 15-27m2/g.
Our company classify the production into three kinds according to the content of SiO2, its physical Properties and chemical properties are as follows:
1:the basic physical properties of Microsilica:
existing form: amorphism thin powder
the typical color: (grey in nature, the color is become darker with the density accretion)
B.E.T Fineness: 15~27 kg/m3
the bulk density: 500-700kg/m3
