Type B silica gel has a smaller specific surface area than Type A silica gel but features large pore sizes, resulting in excellent hygroscopicity under relatively high relative humidity. It is primarily used in products requiring humidity control. It is also used as a fragrance gel by adding desired colors and scents.

Characteristics and Uses

• It consists of high-purity, amorphous SiO2 molecules.
• It is colorless and odorless, appearing as coarse granules or round beads.
• It has a very large surface area due to numerous fine pores.
• It is non-chemically resilient, does not corrode, and does not dissolve easily in water.
• It is classified into Type A, Type B, Type AB, etc., based on its characteristics.
