ûi Site» Qefc Davison pioneered in the development o f die first commercially useful silica gel more than three decades ago, and for years has been America's leading producer. Silica gel, with its porous amorphous physical structure providing a surface area o f 90,000 square feet per cubic inch, is a unique compound of continuing importance and increasing application. Silica gel's most important properties are its ability t o condense and retain condensable gases in the porous structure and its regenerable nature through the application of heat or other elutriation methods. A -wide variety o f partide sizes, densities and adsorptive capacities are available, each having been developed t o meet specific application demands. Investigate Davison Silica Gel, now.
