Titanium-based Lead Dioxide (Ti-PbO₂) Anode Plate for Copper or Zinc EW
| Alloy Composition | Titanium (Ti) and Lead Dioxide (PbO₂) |
| Effective Plate Area | 2 Square Meters for Both Sides |
| Application for | Copper EW / Eletrolysis and Zinc EW |
| Service Life | 5 ~ 8 Years for Copper EW 1.5 ~ 2 Years for Zinc EW |
Why Do You Prefer Titanium-based Lead Dioxide Used in Copper Electrowinning / Electrolysis or Zinc Electrowinning?
1. Extended Service Life:
With a documented lifespan exceeding 2 years (50% longer than traditional lead anodes) in zinc EW, it minimizes replacement frequency and downtime. The titanium base ensures dimensional stability, resisting deformation even under high-current conditions.
2. Cost Efficiency:
- Procurement cost: When the total price of titanium metal used in an anode plate is lower than or not much higher than the total price of lead metal used, it is more cost-effective to choose a titanium-based lead dioxide anode.
- Operation and maintenance cost: Lower energy consumption and maintenance costs.
3. Lightweight & Structurally Stable:
Constructed from Grade 1/2 titanium substrates, the anode combines exceptional strength with low weight. The base material can be reused after recoating, reducing long-term material costs and waste.
4. High Catalytic Activity & Corrosion Resistance:
The electrodeposited lead dioxide coating (β-PbO₂) exhibits excellent electrocatalytic properties for oxygen evolution, reducing energy consumption. It withstands aggressive electrolytes (e.g., high H₂SO₄, Cl⁻, F⁻ concentrations) with minimal corrosion or passivation.
5. Enhanced Current Efficiency:
Achieves 91–95% current efficiency (vs. 89–91% for lead anodes), promoting uniform metal deposition and higher-quality cathode outputs (e.g., LME Grade A copper or ASTM B6 SHG zinc (99.995%)).
