Component Specifications

Definition
A zinc matrix is the engineered structural framework within high-purity zinc anode slabs that provides mechanical stability, uniform current distribution, and controlled dissolution characteristics during electrochemical processes. It serves as the primary conductive substrate that supports the active zinc material while maintaining dimensional integrity under operational conditions.
Working Principle
The zinc matrix operates as the conductive backbone in electrochemical cells, facilitating electron transfer while controlling the dissolution rate of zinc during oxidation reactions. It maintains structural integrity through controlled porosity and alloy composition to ensure consistent performance throughout the anode's service life.
Materials
High-purity zinc (99.99% Zn minimum) with controlled trace elements (Pb < 0.003%, Cd < 0.002%, Fe < 0.001%), often alloyed with aluminum (0.01-0.03% Al) for grain refinement and indium (0.01-0.02% In) for corrosion control.
Technical Parameters
  • Purity 99.99% Zn minimum
  • Density 7.14 g/cm³
  • Porosity 5-15% controlled
  • Grain Size ASTM 5-7
  • Tensile Strength 110-140 MPa
  • Operating Temperature -20°C to 60°C
  • Electrical Conductivity 16.6 MS/m
Standards
ISO 752, DIN 1706, ASTM B69

Frequently Asked Questions

What is the primary function of a zinc matrix in anode slabs?

The zinc matrix provides structural integrity, uniform current distribution, and controlled dissolution characteristics during electrochemical operations.

Why is high purity essential for zinc matrix materials?

High purity (99.99% Zn minimum) minimizes impurities that can cause uneven corrosion, hydrogen evolution, and reduced electrochemical efficiency.

How does porosity affect zinc matrix performance?

Controlled porosity (5-15%) allows electrolyte penetration while maintaining mechanical strength, optimizing both dissolution rate and structural stability.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
