ZINC ANODE

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

CHEMICAL STRUCTURE AND DESCRIPTION:

Zinc is a transition metal located in group 12 of the periodic table. It has a hexagonal close-packed (HCP) crystal structure. It is a silvery-gray metal of moderate hardness and ductility. It is brittle at room temperature but becomes ductile at 100-150 °C. It exhibits good corrosion resistance and is particularly preferred in marine environments. It is widely used as an anode in cathodic protection systems, in marine applications (ship hulls, propellers, tanks), for corrosion prevention of pipelines and storage tanks, in electrolysis and metal plating processes, and in the galvanizing industry.

Structural Features:

• Hexagonal close-packed (HCP) crystal structure

• Moderate hardness

• Ductile (when heated)

11. SUMMARY AND CRITICAL WARNINGS

SUMMARY:

Zinc Anode is a high-purity zinc metal product used as an anode material in cathodic protection systems. It has a density of 7.14 g/cm³, melting point of 419 °C, and boiling point of 907 °C. It exhibits good corrosion resistance, particularly in marine environments.

Its most important applications include use in cathodic protection systems (ship hulls, propellers, tanks), for corrosion prevention of pipelines and storage tanks, in electrolysis and metal plating processes, and in the galvanizing industry.

Non-toxic in solid form, but zinc dust may be harmful if inhaled. Zinc dust may ignite spontaneously in air. Storage should be in dry, clean, moisture-free environments.

Key Properties:

CRITICAL WARNINGS:

1. Pyrophoric Dust: Fine zinc dust may ignite spontaneously in air (H250). Avoid dust formation and work under inert atmosphere.

2. Explosion Hazard: Zinc dust can form explosive mixtures in air. Dust control and ventilation are important.

3. Metal Fume Fever: Inhalation of zinc oxide fumes during welding or melting operations may cause metal fume fever. Use respiratory protection.

4. Cathodic Protection: Zinc anodes are the preferred sacrificial anode material in seawater and soil environments. High purity (≥ 99.9%) is critical for performance.

5. Storage: Surface oxidation may occur in humid environments. Store in dry conditions.
