Silica Gel Type B: Medium Pore Desiccant for Liquid Adsorption & Perfume Carrier
Created on 08.26
Introduction: The Balanced Choice for Adsorption and Carrying
Silica gel comes in different pore structures, each suited to specific applications. Fine-pored silica gel excels at capturing small molecules like water vapor, while macro-pored silica gel is ideal for large-molecule catalysis. But what if your application requires a balance between the two?
Silica Gel Type B is a medium-pore silica gel whose structure lies between macro-pored and fine-pored silica gel. With an average pore diameter of 4.5–7.0 nm and a specific surface area of 450–650 m²/g, it offers an excellent combination of adsorption capacity, pore volume, and mechanical strength.
This unique structure makes Silica Gel Type B highly effective as a liquid adsorbent, drier, and perfume carrier. It is also widely used as a catalyst carrier and in the production of silica sands.
What Is Silica Gel Type B?
Silica Gel Type B is a medium-pore form of silicon dioxide. It is available in pellet or lump form, with a milky white, transparent, or translucent appearance.
Key physical properties:
- Pore volume:
0.60–0.85 mL/g
- Average pore diameter:
4.5–7.0 nm
- Specific surface area:
450–650 m²/g
- Structure: between macro-pored and fine-pored silica gel
Its balanced pore structure allows it to adsorb a wide range of substances while maintaining good flow and handling characteristics in industrial processes.

Main Applications
1. Liquid Adsorbents
Silica Gel Type B is mainly used as a liquid adsorbent. Its medium pore structure allows it to adsorb a wide range of impurities and compounds from liquid streams, making it useful in purification and separation processes.
2. Drier
It is used as a drier to remove moisture from gases and liquids. The medium pore size provides good adsorption capacity while allowing efficient regeneration.
3. Perfume Carrier
Silica Gel Type B is an excellent perfume carrier. Its pore structure can hold fragrance molecules and release them slowly over time, making it suitable for air fresheners, functional packaging, and consumer products.
4. Catalyst Carriers
It can be used as a catalyst carrier for various chemical processes. The medium pore structure provides a stable support for active catalytic components.
5. Silica Sands
Silica Gel Type B can also be used in the production of silica sands for different industrial applications.
