Applications

Powder Metallurgy

• Used in sintered alloys, structural parts, and porous metal components.

Battery and Fuel Cell Materials

• Acts as a catalyst support or active material in Ni-based electrodes (e.g., NiMH, alkaline fuel cells).

Electronics and Conductive Pastes

• Applied in thick-film circuits, electromagnetic shielding coatings, and conductive composites.

Catalysis and Nanostructured Materials

• Serves as a precursor in the synthesis of nickel catalysts or metal-organic frameworks (MOFs).

Additive Manufacturing

• Utilized in binder jetting or cold spray metal printing techniques.

Safety

Signal Word: ⚠️ Danger

Hazard Statements:

• H351: Suspected of causing cancer

• H372: Causes damage to organs through prolonged or repeated exposure (inhalation)

• H410: Very toxic to aquatic life with long-lasting effects

Precautionary Statements:

• P260: Do not breathe dust or fumes

• P280: Wear protective gloves, clothing, and respiratory/eye protection

• P314: Get medical advice/attention if you feel unwell

• P391: Collect spillage

• P501: Dispose of contents/container according to local environmental regulations

Handling and Storage

• Handling: Avoid dust formation. Use local exhaust ventilation. Wear appropriate PPE including dust mask or respirator (P3 recommended).

• Storage: Store in a tightly sealed, labeled container in a cool, dry, and well-ventilated area. Avoid contact with oxidizing agents and acids.

• Explosion Risk: Finely divided metal powder may pose a dust explosion hazard in air – handle with grounding and spark protection precautions.

Environmental Considerations

Nickel compounds are hazardous to aquatic ecosystems. Prevent uncontrolled discharge into soil or water. Use appropriate waste collection procedures for disposal or recycling.
