White Silica Gel

Character: Fine-pored silica gel includes fine-pored spherical silica gel and fine-pored lumpy silica gel, which are transparent or semitransparent glasslike in appearance.

Average pore diameter: 2. 0-3.0nm

Specific surface: 650-800m2/g,

Pore volume: 0.35-0.45ml/g

Specific heat: 0.92KJ/kg. ℃

Heat conductivity: 0.63KJ/m. Hr. ℃

Fine-pored silica gel is also called Type-A silica gel.

Purpose: The gel is mainly used for desiccation and moisture absorption, and as catalyst carrier, adsorbent, separating agent and pressure-swing absorber as well.
