· Silicagel
  • Silica-gel is an absorbent made by solidifying the colloidal solution of silicic acid. It's also called anti humidity agent or humidity absorbing agent. During World War I, Dr. Walten A. Patrick from John Hopkins University invented it as an absorbent for GAS MASK container.

  • CAS No. 1343-98-2
· Property
  • The term of gel expresses its morphological status, and its usual structure has hard glassy status materials and transparent SiO2 bond networks.
    The surface area of fine pores of Silica-gel depends on manufacturing method but the surface area of internal pores of diameter 1/16 inch is 250,000 times of the external surface area.
    Silica-gel is a group of granular amorphous particles where fine holes are connected to each other in an extensive mesh and its huge surface area (1g에 300~400㎡) promotes natural absorbing and condensation phenomena which lead to excellent absorbing capability for water, alcohol, and other compounds. It's no color and no smell and it's a dehumidifying agent not harmful to human body.
