BEHAVIOR OF SILICA IN ION EXCHANGE AND OTHER SYSTEMS By Peter Meyers / ResinTech Inc. IWC9964 INTRODUCTION Silica is the second most abundant element found on earth. Although silicon itself (Si) is a glassy insoluble solid, the various oxides (primarily "SiO2") are somewhat soluble in water. Indeed, all natural

Silicagel Silica Types Fuji Silysia Chemical Ltd. (FSC) is a manufacturer of synthetic amorphous silica, a formation of silicon dioxide that is tasteless, colorless and odorless. The term silicagel is derived from the manufacturing method, solgel, to produce this material.
The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.
