Chemical Family: Rare Earth Metal Nitrate Salt
Synonyms: Neodymium(III) nitrate hexahydrate
CAS Number: 16454-60-7
Recommended Use: Research, industrial catalyst, specialty glass manufacturing
Supplier Contact: Hazard response and technical inquiries typically handled by chemical safety departments; always review latest supplier data.
Classification: Oxidizing solid (Category 3), Acute toxicity (Oral) Category 4, Eye irritation Category 2A
Signal Word: Warning
Hazard Statements: Harmful if swallowed. Causes serious eye irritation. May intensify fire; oxidizer.
Pictograms: Exclamation mark, oxidizer, health hazard symbols.
Precautionary Statements: Keep away from heat, sparks, open flames. Store away from combustible materials. Wear protective gloves, eye protection, and clothing during handling. Avoid inhaling vapors, dust, or mists. Wash thoroughly after handling.
Chemical Identity: Neodymium Nitrate Hexahydrate
Percent by Weight: ~98%
Neodymium Content: Approximately 18-22%
Impurities: Trace rare earth oxides, possible trace nitrates of other rare earth elements.
Other Constituents: Water of crystallization (approximately 6 molecules per formula unit).
Inhalation: Move to fresh air. If difficulty breathing or irritation persists, seek medical attention. Individuals who have respiratory conditions may react more severely.
Skin Contact: Remove contaminated clothing and rinse skin with running water for at least fifteen minutes. Wash with soap to remove any residual material.
Eye Contact: Flush eyes with water for several minutes, lifting eyelids to ensure complete rinsing. Remove contact lenses if present and safe. Medical attention needed if irritation develops or persists.
Ingestion: Rinse mouth with water. Do not induce vomiting unless instructed by poison control. Seek medical attention for symptoms such as nausea, vomiting, or abdominal pain.
Suitable Extinguishing Media: Use water spray, dry chemical, or carbon dioxide. Foam may also be effective.
Unsuitable Extinguishing Media: Do not use dry combustibles or halons; oxidizer accelerates burning.
Specific Hazards: Product accelerates combustion. Fire may release toxic/irritant gases including nitrogen oxides.
Protective Equipment: Full chemical-resistant gear, self-contained breathing apparatus. Remain upwind and avoid inhaling fumes.
Additional Information: Cool containers with water spray to prevent rupture. Isolate incident area and deny unnecessary entry.
Personal Precautions: Evacuate area and limit entry. Use recommended PPE including gloves, goggles, and a respirator.
Environmental Precautions: Prevent run-off into water systems. Contaminated waste should not reach sewers or surface water.
Containment and Cleanup: Absorb spilled material with inert, non-combustible absorbent (sand, earth). Carefully collect, avoiding dust generation. Store in appropriate containers for hazardous waste disposal.
Decontamination: After removal, thoroughly wash area with water to clear residues. Ventilate area as needed.
Handling: Work in well-ventilated areas or under local exhaust. Keep away from heat, sparks, and incompatible materials like organic substances and strong reducing agents. Use non-sparking tools and explosion-proof equipment.
Storage: Store in tightly closed containers, protected from moisture and light. Place in a cool, dry area separate from combustible substances. Use corrosion-resistant shelving due to potential for nitric acid release. Periodic inspection ensures container integrity.
Exposure Limits: No specific national occupational exposure limits, but minimize exposure as good industrial hygiene practice.
Engineering Controls: Ensure effective local exhaust ventilation at points of dust/vapor release.
Respiratory Protection: Use NIOSH/MSHA approved particulate respirator if airborne concentrations exceed recommended levels.
Skin Protection: Nitrile gloves recommended for direct handling. Protective clothing to cover exposed skin.
Eye Protection: Chemical splash goggles required; face shield recommended when transferring bulk powder.
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling, and before eating or drinking. Remove contaminated clothing and launder before reuse.
Appearance: Light purple, crystalline solid
Odor: Odorless
Melting Point: Approximately 75°C (decomposition begins in hydrated form)
Solubility: Soluble in water
Boiling Point: Not applicable (decomposes on heating)
Vapor Pressure: Negligible at room temperature
Density: 2.1 – 2.2 g/cm³ (hydrated solid)
pH (1% solution): Acidic, around 2-3
Oxidizing Properties: Strong oxidizer
Chemical Stability: Stable under recommended storage conditions, moisture and heat accelerate decomposition.
Incompatible Materials: Strong reducing agents, organic materials, metals, sulfur, phosphorus.
Hazardous Reactions: Can react with combustibles and reducing substances to cause fire/explosion.
Decomposition Products: Nitrogen oxides, neodymium oxide, oxygen.
Polymerization: Will not occur.
Acute Toxicity: Harmful if swallowed. LD50 (oral, rat) not well defined for neodymium nitrate but listed as moderate hazard.
Chronic Effects: Repeated exposure may target liver and kidneys due to rare earth accumulation. No indication of carcinogenicity in current literature.
Routes of Exposure: Inhalation, skin/eye contact, ingestion.
Symptoms: Irritation to mucous membranes, burning in throat, coughing, abdominal pain, vomiting, eye redness, watering.
Additional Notes: Data on reproductive toxicity is limited, use caution to minimize exposure.
Toxicity: Toxic to aquatic organisms at high concentrations. Disrupts algae and aquatic invertebrate growth cycles.
Persistence/Degradability: Nitrate anion can contribute to soil and water eutrophication.
Bioaccumulation: Potential for rare earth elements to accumulate within aquatic and terrestrial ecosystems, with slow degradation.
Mobility: Highly soluble in water, risk of migration through soil and surface water dispersion.
Precautions: Avoid uncontrolled discharge and spillage into surface waters.
Waste Treatment: Treat as hazardous waste. Incinerate only when permitted by regulations.
Packaging Disposal: Rinse empty containers and manage through hazardous waste procedures.
Additional Measures: Waste contractors must comply with local, regional, and national laws for hazardous substances. Do not sewer.
