Additional FAQs on Nickel Nanopowder

1) How do I prevent oxidation and agglomeration during storage and handling?

• Store nickel nanopowder in sealed containers under dry inert gas (argon) with desiccant, at <20% RH and room temperature. Use anti-static tools, minimal shear, and, if compatible with the application, surface passivation or organic capping agents. Avoid repeated container opening; portion into aliquots.

2) Which synthesis routes are most common and how do they affect properties?

• Chemical reduction (e.g., hydrazine/borohydride) yields small particles with high surface area but often requires surfactant removal. Thermal decomposition and polyol methods offer narrow size distributions. Gas-phase routes (plasma, flame, laser ablation) produce high-purity powders but at higher cost. Route selection impacts particle size, crystallinity, carbon/oxygen residue, and magnetic behavior.

3) Can nickel nanopowder be sintered into dense parts at low temperature?

• Yes, compared to micron powders, Ni nanopowders sinter at lower temperatures (typically 400–700°C depending on size and surface chemistry). Controlled ramp/debinder steps and reducing atmospheres (H2/N2) help achieve high density while limiting grain growth.

4) What safety measures are essential for lab-scale use?

• Follow nanoparticle-specific PPE: fitted respirator (P100), lab coat, nitrile gloves, eye protection. Handle in HEPA-filtered fume hood or enclosure. Implement grounded equipment to reduce static. Manage waste as potentially hazardous (nickel compounds are sensitizers); consult SDS and local regulations.

5) How does particle size influence catalytic activity and magnetism?

• Catalysis generally benefits from smaller particles (higher active surface), but too-small sizes may suffer from sintering during reaction. Magnetic saturation decreases with reduced size, and superparamagnetism may appear below ~10–20 nm, impacting applications in separations and MRI contrast design.

2025 Industry Trends for Nickel Nanopowder

• Battery materials integration: Nickel nanopowder and Ni-based nano-alloys are increasingly explored for conductive scaffolds/current collectors in next-gen Li-ion and solid-state batteries.
