Silica gel is made of silicon dioxide, essentially, porous sand. It is used to r educe condensation and allows the stored item to stay dry even during humid, damp conditions. You find them in bottles or packages when you buy vitamins, purses, shoes, even computer equipment.
There are 1,724 silica gel sand suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Pakistan, and Australia, which supply 99%, 1%, and 1% of silica gel sand respectively. Silica gel sand products are most popular in North America, Southeast Asia, and South America.
Silica-gel & 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 silica-gel is derived from the manufacturing method, sol-gel, to produce this material.
Silica gel is form of silicon dioxide, Si02, the material that occurs in nature as sand. The difference between silica gel and sand is that sand is a crystalline, non-porous form, whereas silica gel is non-crystalline and highly porous. Silica gel is synthetically manufactured from the chemical reaction between sodium silicate and sulfuric acid.
