Overview
Microporous titanium discs are precision-engineered components fabricated from commercially pure titanium or titanium alloys. These discs feature uniformly distributed pores created through powder metallurgy, laser drilling, or chemical etching processes. Their unique structure combines the inherent benefits of titanium – including exceptional corrosion resistance and strength – with tailored permeability. This makes them indispensable in industries requiring controlled fluid or gas flow through a durable metallic medium.
Structure and Working Principle
The discs typically range from 0.1mm to 5mm in thickness with diameters from 5mm to 300mm. Porosity can be customized between 10-40% void volume, with pore sizes precisely controlled from sub-micron to 100 microns. Functionally, they operate as selective barriers where the pore size determines which particles or molecules can pass through. In filtration applications, this creates a sieving effect, while in gas diffusion systems it enables controlled mixing. The open-cell structure maintains structural integrity while allowing passage of desired media.
Key Features
Titanium's natural oxide layer provides outstanding resistance to acids, alkalis, and salt solutions, far surpassing stainless steel in harsh environments. This makes microporous titanium discs suitable for aggressive chemical processing applications. The material's biocompatibility has led to widespread adoption in medical devices, particularly as fusion cages in spinal implants where bone ingrowth through the pores is desired. Their high melting point (1668°C) allows use in high-temperature processes where polymer membranes would fail.
Application Areas
In the chemical industry, these discs serve as spargers for gas introduction and as electrode substrates in electrolytic cells. Aerospace applications include fuel cell components and hydraulic system filters. The medical field utilizes them for dental implant barriers and prosthetic interfaces. Emerging uses include 3D printing substrates and catalyst supports in green energy systems, leveraging titanium's stability under photocatalytic conditions.
Maintenance and Precautions
While titanium discs are highly durable, proper handling ensures longevity. Ultrasonic cleaning with mild detergents is preferred over mechanical scrubbing to preserve pore structure. For industrial applications, pre-filtration of process streams is recommended to prevent premature pore clogging. In medical settings, they require sterilization via autoclaving (up to 135°C) or gamma irradiation rather than chemical sterilants that might leave residues.
B2B Procurement Guide
Technical specifications should clearly define: pore size distribution (average and maximum), porosity percentage, thickness tolerance (±0.05mm typical), and material certification (ASTM F67 or F136 for medical grade). Lead times for custom configurations range from 4-8 weeks. Bulk orders (100+ units) typically qualify for 15-30% discounts. Quality verification should include bubble point testing for pore size validation and metallurgical analysis for material purity.
