Multi-stage porous silica microspheres

• Packaging: 5 g; 10 g
• D: 400-900 nm

• High temperature resistance and chemical stability: Multi-stage porous silica microspheres can withstand higher temperatures and are stable to organic solvents.
• Adjustable pore size and volume: Through different preparation methods and parameter adjustments, our company can provide different pore sizes and distributions to meet the needs of client-specific applications.
• High specific surface area: Multi-stage porous silica microspheres have very high specific surface area due to their unique multi-stage pore structure, which plays a key role in adsorption and separation, catalyst support and so on.
• Good Dispersion and Morphology Control: Multi-stage porous silica microspheres are usually well monodisperse with controllable particle size and pore size, which helps to improve their performance in various applications.
