Porous titanium (sintered titanium, foamed titanium) is widely used in the pharmaceutical industry, water treatment industry, food industry, bioengineering, chemical industry, petrochemical industry, metallurgical industry, and gas purification. Porous titanium can also be used as a gas diffusion layer (GDL) in next-generation fuel cells (PEMFCs).

Porous titanium (sintered titanium) manufacturing process

Preparation of raw titanium powder – cold isostatic pressing – high-temperature vacuum sintering – processing to size – assembly, and filtration as needed

Properties of porous titanium (sintered titanium):

  1. Uniform structure, narrow pore size distribution, and high separation efficiency.
  2. High porosity, low filtration resistance, and high penetration efficiency.
  3. High-temperature resistance, generally 280 degrees.
  4. Good chemical stability, acid and alkali corrosion resistance, and oxidation resistance.
  5. No particles fall off, no secondary pollution to the medium, suitable for food hygiene and pharmaceutical GMP requirements.
  6. It has good mechanical properties and can be used for suction filtration and pressure filtration.
  7. Low-pressure drop, small footprint, and large flow rate.
  8. Good antibacterial ability.
  9. The overall length can be up to 1000 mm, with no welding required.
  10. Can be regenerated online, is easy to clean, and has a long service life (several times longer than ordinary membrane filter elements)

Applications of porous titanium

With its unique properties, porous titanium can be widely used in the pharmaceutical industry, water treatment industry, food industry, bioengineering, chemical industry, petrochemical, metallurgical industry, and gas purification. It is a new material with broad development prospects. Typical uses include:

– In the infusion of the pharmaceutical industry, small injections, eye drops, decarbonization filtration in the concentration of oral liquids, and security filtration before terminal filtration in the lean distribution.              – Removal of impurities in the production process of raw materials, decarbonization filtration, and fine filtration of materials.                       

-Security filtration of ultrafiltration, RO, and EDI systems in the water treatment industry, filtration after ozone sterilization, and ozone aeration.

-Clarification and filtration of beverages, white sprinkles, beer, vegetable oil, mineral water, soy sauce, and vinegar in food and beverage.                                    

-Decarbonization filtration and precision filtration of liquid products, liquid raw materials, and pharmaceutical intermediates in the chemical industry, ultrafine fine bodies, catalyst recovery, precision filtration after resin adsorption, system heat transfer oil, material removal and impurity filtration, catalytic gas Purification and so on.

-Oilfield backflow water filtration, security filtration before reverse osmosis in the desalination field.

-High-temperature decarbonization and de-whitening filtration in the dye industry. 

-Filtration of steam, compressed air, catalyst, etc. in gas purification.

-As an electrolytic electrode, it can maximize the electrolysis area and increase the gas evolution rate.
