| Chemical Composition | Silicon dioxide (SiO2) |
| Physical Form | Granular or beaded |
| Pore Size | Varies based on type (fine to coarse) |
| Moisture Absorption | Can absorb up to 40% of its weight in moisture |
| Reusability | Can be regenerated by heating to remove absorbed moisture |
| Non-Toxic | Safe for use in food and pharmaceuticals |
| Temperature Stability | Effective in a wide range of temperatures, typically from -40°C to 100°C |
Types of Silica Gel
Silica gel comes in various types, each designed for specific applications. The following table outlines the differences between the main types of silica gel:
| Type | Characteristics | Applications |
|---|---|---|
