Micro Silica Chemical Composition
Basic physical properties of micro silica: ◇ Existing form: amorphous ultra-fine (amorphous) powder ◇ Typical color: gray (the natural state is grayish white, and the color gradually deepens with the increase of density) ◇ Specific surface area: 15~28 m2/g ◇ Loose bulk density: 200~350 kg/m3 ◇ Activity index: ≥ 85%…
