Product Introduction

In precision electrolysis and electrochemical machining, the uniformity and corrosion resistance of the diffusion layer directly determine product yield and electrode life. This titanium filter plate from TOPTITECH-50mm in diameter, 0.5mm in thickness, and 20μm in absolute filtration rating-is manufactured using high-purity titanium powder through three core processes: compression molding, vacuum sintering, and precision laser cutting. During vacuum sintering, controlled atomic diffusion and neck growth occur between titanium particles, forming a three-dimensional interconnected porous structure with an extremely tight pore size distribution.

 

This filter plate maintains long‑term stability in strong acids, strong alkalis, and fluoride‑containing electrolytes. The ultra‑thin 0.5mm structure greatly reduces internal resistance and concentration polarization in the electrolytic cell, while the 20μm filtration rating effectively intercepts anode slime and byproduct particles, protecting ion‑exchange membranes or diaphragms. As a core component of electrolysis systems, it is suitable for both laboratory‑scale cells and industrial modules, significantly improving current efficiency and product consistency.

Precise Porous Structure for Uniform Flow

Porosity reaches 30–40% after sintering, with three‑dimensional tortuous micro‑channels that generate micro‑turbulence during electrolyte passage, eliminating dead zones and keeping current density variation below 5%.

Ultra‑Thin yet Strong, Low Resistance & High Efficiency

At 0.5mm thickness, it combines structural rigidity (bending strength ≥120MPa) with low flow resistance, reducing pressure drop by approximately 40% compared to conventional 1mm titanium plates, which considerably lowers pumping energy consumption.

Excellent Corrosion Resistance & Long Service Life

The titanium substrate spontaneously forms a dense TiO₂ passive film under anodic oxidation conditions, withstanding electrolytes at pH 0–14 and chloride concentrations up to 200g/L, and delivering a continuous operating life exceeding 8,000 hours.

Controllable Precision & Lot‑to‑Lot Consistency

Each batch undergoes testing using a bubble point pore size analyzer and a 3D optical profilometer to guarantee an absolute filtration rating of 20μm, with a pore size deviation ≤3μm between batches, facilitating standardized electrolysis processes.

 applications

 

Chlor‑Alkali Electrolysis

Used as the anodic diffusion layer in ion‑exchange membrane cells, it uniformly distributes saturated brine and collects chlorine gas while blocking detached coating particles, protecting the membrane from mechanical damage.

 

Hydrometallurgy (Copper, Nickel, Cobalt Electrowinning)

Installed as an intermediate diffusion layer between the cathode and anode, it improves metal ion mass transfer, reduces the likelihood of dendrite growth, and extends the cathode stripping cycle by more than 30%.

 

Hydrogen Production via Water Electrolysis

Adapted as the anodic porous transport layer (PTL) in PEM electrolyzers, it promotes rapid bubble detachment at low voltages (1.8–2.2V), reduces ohmic polarization, and increases hydrogen production efficiency by 12–18%.

 

Electrochemical Synthesis (Specialty Chemicals / Pharmaceuticals)

Used in laboratory or pilot‑scale electrolysis devices as a supporting diffusion layer for the working electrode, ensuring uniform reactant contact with the electrode surface-especially critical for fine synthesis processes requiring strict control of side reactions.
