high-purity porous alumina ceramic diaphragm tubes for chromic–sulfuric ABS etch electrolysis.

Porous Ceramic Diaphragm for Electrolysis Industry

Our porous ceramic diaphragm is a core component engineered for electrolytic processes, crafted from high-purity alumina or cordierite-mullite via high-temperature sintering. Designed with a uniform, controllable microporous structure, it delivers reliable ion permeability and precise separation of anode and cathode compartments, critical for efficient electrolysis.

It features exceptional chemical stability, resisting strong acids, alkalis, and corrosive electrolytes, ensuring long-term performance without degradation. High mechanical strength and thermal shock resistance prevent cracking under harsh operating conditions, extending service life. The optimized porosity enables efficient ion flow with low electrical resistance, promoting uniform current distribution and high electrolytic efficiency.

Widely applied in hypochlorous acid generation, chrome electroplating, wastewater treatment, and chemical synthesis, it supports stable, eco-friendly, and cost-effective electrolytic operations . Customizable sizes and shapes adapt to diverse electrolyzer models, making it an ideal choice for industrial electrolysis systems.
