Lanthanum suspension is typically formed by dispersing lanthanum oxide (La₂O₃) or lanthanum hydroxide nanoparticles in a liquid medium. The nano-sized particles exhibit unique properties due to their high surface area and reactivity. Lanthanum oxide nanoparticles can exhibit needle-like morphology and cubic crystallinity.

No CAS Number: Lanthanum suspensions are manufacturer-specific formulations and do not have a standard CAS number. Refer to supplier documentation for product specifications.
Sedimentation: Nanoparticles tend to settle over time. Must be shaken well before use.
Stabilization: Particles may agglomerate without proper stabilizer. Must be stored according to product specifications.
Nanoparticle Safety: Standard safety precautions for nanoparticle inhalation and skin contact should be followed.
Application Optimization: Each application requires optimization of particle size, solvent, and stabilizer selection.
Storage:
Store in a cool, dry, well-ventilated area
Keep in original packaging under inert atmosphere
Do not freeze (refrigeration depends on product specifications)
Handling:
Shake well before each use
Ultrasonic bath homogenization recommended
Ensure proper ventilation to avoid powder inhalation
Use gloves and protective goggles
Waste Management:
Dispose in accordance with local regulations
Consider recycling options for rare earth recovery
