Porous titanium plates are made from high-purity titanium powder by cold isostatic pressing and vacuum sintering - rigid, interconnected and fibre-shedding free - for electrolyzer gas diffusion layers, precision liquid filtration and gas distribution, with porosity and rating customizable.
Titanium powder is screened into narrow size fractions, cold-isostatically pressed and vacuum sintered, so particles bond metallurgically into interconnected pores. The result is a rigid porous metal body with no membrane, no binder and no fibre shedding; pore size is controlled by the powder fraction, keeping the filtration rating stable, and the plate can be cleaned and reused repeatedly.
The powder fraction sets the pore distribution, isostatic pressing keeps density uniform through the thickness, and vacuum sintering gives the plate its strength and corrosion resistance. Porosity of about 25-50 percent and filtration ratings of 5-100 microns can be tailored to the application; blinded plates regenerate well by backwashing, ultrasonic cleaning or acid soak. Pure titanium resists chlorides and a wide range of acids and alkalis, with a continuous wet-service temperature of about 300 degrees C.
Gas diffusion layers for PEM/AEM electrolyzers and fuel cells, precision filtration of pharmaceutical and food liquids, gas sparging and distribution in chemical processing, vacuum holding and gas back-pressure control. Squares, discs, rings and machined profiles available to order.
All data above are obtained under specific test conditions; the actual solution must be engineered to site conditions. AIFILTECH provides custom design and sizing based on actual gas volume, temperature, dust characteristics and emission limits.
