Description of the porous titanium disc
The porous titanium disc is a filtration material produced from industrial high-purity titanium powder (>99,4%) by powder classification, moulding, sintering and mechanical welding procedures. Its porosity and filtration precision can be adjusted over a wide range. Porous titanium exhibits an open cellular structure and, owing to its low elastic modulus, bioactivity, biocompatibility and capacity for bone regeneration, it is used as an implant material.
Features of the porous titanium disc
- Interconnected pores that permit the passage of air and water
- Small, uniformly distributed pores
- Flat external surface and flat interior of the pores
- Large specific surface area
- Various surface treatments

Applications of porous titanium sheet
- Porous titanium sheet and porous stainless steel sheet are used as a gas diffusion layer (GDL) in polymer electrolyte membrane fuel cells (PEMFC).
- Porous titanium sheets and tubes can be assembled into titanium filters for filtration under high-temperature and corrosive conditions.
- Porous titanium may be coated with Pt and other elements for use as an anode.
