Description of Porous Titanium Tube
The porous titanium tube is a filter material produced from industrial high-purity titanium powder (>99.4%). The tube is manufactured by powder classification, forming, sintering and mechanical welding methods. Its porosity and filtration precision can be adjusted over a wide range. Porous titanium exhibits an open cellular structure and is used as an implant material due to its low elastic modulus, proven bioactivity, biocompatibility and capacity for bone regeneration.
Features of the Porous Titanium Tube
- Interconnected pores that permit the passage of air and water
- Small pores that are uniformly distributed
- Flat external surface and flat internal pore surfaces
- High specific surface area
- Various surface treatments

Applications of Porous Titanium Tubes
- Porous titanium sheets and porous stainless steel sheets are used as a gas diffusion layer (GDL) in polymer electrolyte membrane fuel cells (PEMFC).
- Porous titanium sheets and tubes are assembled into titanium filters that operate at high temperatures and in corrosive environments.
- Porous titanium may be coated with Pt and other elements for use as the anode.
