Product Name: Iron-Cerium Alloy
Chemical Formula: Fe-Ce
Synonyms: Ferrocerium, Iron/Cerium Master Alloy
Manufacturer: Please consult your supplier’s documentation
Recommended Use: Alloying element in metallurgy, ignition devices, special steels
Contact Information: Supplier details and emergency number provided on packaging
REACH Registration Number: Available on request
Classification: Not classified as hazardous under GHS for bulk alloy; fine particulates may present a hazard
Physical Hazards: Dust and powder forms present fire and explosion risk
Health Hazards: Prolonged skin contact may cause irritation; inhalation of dust or fumes can impact respiratory system
Environmental Hazards: Cerium poses low aquatic toxicity but can disrupt soil microorganisms
Label Elements: No specific symbol for alloys; use exclamation mark for dust
Important Symptoms: Cough, sore throat, eye and skin irritation
Substances: Mixture
Iron (Fe): 70–90% by weight; CAS: 7439-89-6
Cerium (Ce): 10–30% by weight; CAS: 7440-45-1
Impurities: Trace rare earth elements, possible small quantities of lanthanum, praseodymium, neodymium
Additives or Stabilizing Agents: Not typically added
Inhalation: Move to fresh air, seek medical advice for persistent cough or wheezing
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing
Eye Contact: Rinse immediately with water for at least 15 minutes, seek medical attention if irritation persists
Ingestion: Rinse mouth with water, do not induce vomiting, get medical help
Most Critical Symptoms: Persistent respiratory difficulties, severe eye irritation, allergic reactions
Special Notes for Physicians: Treat symptomatically; exposure to fine dust or fumes requires monitoring for delayed lung symptoms
Suitable Extinguishing Media: Class D fire extinguisher, dry sand, graphite powder
Unsuitable Extinguishing Media: Water and regular chemical fire extinguishers increase combustion or explosion risk
Special Hazards: Fines can ignite spontaneously in air, burning produces metal oxide fumes
Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus
Advice for Emergency Responders: Move combustibles away, stay upwind of fumes
Explosion Sensitivity: Finely divided powder becomes airborne, may create explosive dust-air mixtures
Personal Precautions: Use respiratory protection, avoid dust generation, ventilate area
Environmental Precautions: Prevent release to watercourses and drains, collect residues for disposal
Spill Response: Sweep up material with spark-proof tools, avoid water, collect in containers for recovery or disposal
Methods for Cleaning Up: Use HEPA-filtered vacuum or wet methods for dust, never use compressed air
Safe Handling Advice: Work in well-ventilated area, avoid creation of dust, refrain from eating or drinking in work zones
Technical Measures: Ground all transfer equipment against static discharge, avoid mechanical shock
Storage Conditions: Keep dry, store in tightly closed containers, segregate from acids and oxidizers
Incompatible Materials: Strong oxidizers, acids, halogens
Specific End Uses: Industrial melting and synthesis processes, not for direct human exposure or medicinal purposes
Occupational Exposure Limits: Iron dusts/fumes: 5 mg/m³ (TLV-TWA, ACGIH); Cerium: 1 mg/m³ (inhalable, recommended)
Engineering Controls: Local exhaust ventilation, downdraft tables, dust collection systems
Personal Protective Equipment: Safety goggles, protective gloves resistant to chemicals, flame-retardant clothing
Respiratory Protection: Approved particulate respirators for dust or fume generation
Environmental Controls: Regular air monitoring, maintain closed systems for bulk handling
Appearance: Silvery or gray solid, can be manufactured as rod, strip, or powder
Odor: Odorless
Melting Point: 800–1,500°C depending on composition
Boiling Point: >2,000°C
Density: 6.5–7.0 g/cm³
Solubility: Insoluble in water
Flash Point: Not applicable as solid; powders: risk of ignition in air
Explosive Properties: Dust may form explosive mixture with air
Vapor Pressure: Negligible at room temperature
Chemical Stability: Stable in solid bulk form under normal conditions
Conditions to Avoid: Moisture, open flames, high temperatures, mechanical shock causing dust generation
Incompatible Substances: Water, strong oxidizers, mineral acids
Hazardous Decomposition Products: Cerium and iron oxides, hydrogen gas in contact with acid or moisture
Hazardous Reactions: Sudden oxidation in presence of fine dust and air or water
Acute Toxicity: Low toxicity in bulk form; dusts/fumes can irritate nose, throat, and lungs
Chronic Effects: Prolonged exposure to dust may lead to pneumoconiosis, lung dysfunction
Skin Corrosion/Irritation: Prolonged contact may cause mechanical irritation
Eye Damage/Irritation: Dust particles can scratch or irritate eyes
Respiratory Sensitization: No strong evidence of sensitization; monitor for allergic or asthmatic response
Ingestion: Not likely by industrial use, but accidental consumption can lead to gastrointestinal upset
Carcinogenicity: Iron and cerium not classed as known carcinogens; welding fumes from alloy can pose risk
Toxicity to Aquatic Life: Cerium shows low direct aquatic toxicity, but accumulation alters algae and invertebrate community health
Persistence and Degradability: Not rapidly degraded or bioaccumulated; particles settle in sediment
Bioaccumulative Potential: Unlikely for bulk metals, but fine particles can deposit in biota
Mobility in Soil: Limited solubility means metals remain localized near discharge point
Other Environmental Effects: Release to water and soil should be minimized; avoid large-volume spills
Wastewater Precautions: Prevent entry into sewage or public waterways
Waste Treatment Methods: Recover and recycle where feasible, dispose of through licensed hazardous waste contractor
Disposal of Contaminated Packaging: Rinse containers if suitable for recycling, otherwise treat as hazardous waste
Laws and Regulations: Comply with local, regional, and national regulations for non-ferrous alloys
Incineration or Landfill: Never incinerate; landfill only if recycling not possible, using properly permitted facility
UN Number: Not assigned for bulk alloy; powder may qualify for UN 3089 (Metal Powders, Flammable, n.o.s.)
Transport Hazard Class: Not regulated for solid blocks; dust or powder: Class 4.1 (flammable solid)
Packing Group: III (for powder forms)
Special Precautions: Protect from moisture; avoid generating airborne dust during loading/unloading
DOT/IATA/IMDG: Check individual shipment for correct classification based on particle size and packaging
Environmental Hazards: Not a marine pollutant
Transport Labeling: Use appropriate flammable solid label for fine particulates or powder
OSHA Status: Bulk alloy not listed as hazardous; iron and cerium dusts/fumes regulated by permissible exposure limits
TSCA: Iron and cerium listed
REACH: Substance complies, as required by EU regulations
