Porous Ceramic Diaphragm for Electrochemical Cells

Porous Ceramic Diaphragm is a high-performance inorganic ceramic component designed for electrochemical separation applications.

Manufactured from high-purity ceramic materials through advanced forming and sintering processes, it provides excellent chemical stability, mechanical strength, and long-term durability in demanding operating environments.

The controlled porous structure enables efficient ion transfer while maintaining effective separation between different reaction chambers, making it suitable for various electrochemical systems.

Compared with conventional polymer separators, ceramic diaphragms offer superior resistance to chemical corrosion, temperature variation, and mechanical stress, providing a longer service life in harsh conditions.

The ceramic structure provides excellent resistance against:

• Acidic environments
