Type A Fine-pored White Silica Gel
Character:
Fine-pored silicagel 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. °C
Heat conductivity: 0.63KJ/m. Hr. °C
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.
