Description of the Porous Titanium Cup
The porous titanium cup is a porous filter material produced from industrial high-purity titanium powder (>99.4 %) via powder classification, forming, sintering and mechanical welding processes. Its porosity and filtration precision can be adjusted over a wide range. Porous titanium features an open cell structure and, due to its low elastic modulus, excellent bioactivity, biocompatibility and its ability to promote bone regeneration, is a promising implant material.
Features of the Porous Titanium Cup
- Interconnected pores permitting the flow of air and water
- Small pores uniformly distributed
- Flat external surface and flat internal pore surfaces
- High specific surface area
- Various surface treatments

Applications of the Porous Titanium Cup
- Porous titanium plate and porous stainless-steel plate may serve as gas diffusion layers (GDL) in polymer electrolyte membrane fuel cells (PEMFC).
- Porous titanium plates and tubes may be assembled into titanium filters for filtration at high temperatures and in corrosive environments.
- Porous titanium may be coated with Pt and other elements that may be employed as anodes.
