Fine porous
silica gel
, also called Type A silica gel, includes fine porous spherical silica gel and fine porous blochy silica gel. The appearance is transparent or translucent The average pore diameter is 2.0-3.0 mm, surfacearea is 650-800m²/g;the pore volume is 0.35-0.5ml/g; specific heat is 0.92 KJ/kg * ºC .
Mainly used for drying and moisture proof, may also be used as catalyst carriers, adsorbents, separators and variable pressure adsorbents, etc.
