Composition / Information on Ingredients

Chemical Formula: Zr(HPO4)2·H2O
Ingredient: Zirconium(IV) Hydrogen Phosphate
CAS Number: 13772-29-7
Percentage: >98% by weight
Impurities: Water of hydration, possible trace metals depending on synthesis process

First Aid Measures

Inhalation: Move person to fresh air, keep comfortable, seek medical attention if respiratory symptoms develop or persist
Skin Contact: Wash with soap and water, remove contaminated clothing; seek attention if irritation happens
Eye Contact: Rinse carefully with water for several minutes, remove contact lenses, continue rinsing, get medical help if irritation remains
Ingestion: Rinse mouth, drink water if conscious, avoid inducing vomiting, seek medical advice if feeling unwell

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Specific Hazards from Fire: Material does not burn easily, releases oxides of phosphorus and zirconium when heated extremely
Advice for Firefighters: Wear self-contained breathing apparatus and full protective gear, avoid inhaling smoke or fumes from thermal decomposition
Additional Information: Keep nearby containers cool with water spray to avoid pressure build-up or rupture

Accidental Release Measures

Personal Protection: Use gloves, dust mask, goggles; avoid dust generation
Spill Response: Sweep up dry spills with care, minimize airborne dust, use a wet method if practical
Environmental Precautions: Keep material from drains or soil; collect in containers for disposal
Clean-up Method: Pick up using tools or damp cloth, place in labeled waste bin, ventilate area after major dusting

Handling and Storage

Handling Guidelines: Avoid creating dust clouds, use tools for scooping, wash hands after contact
Storage Conditions: Keep container closed, store in cool, dry, and well-ventilated area
Incompatible Materials: Reacts strongly with alkalis, avoid mixing with acids beyond neutral pH
Storage Life: Retains properties if kept sealed from humidity and reactive materials
Recommended Packaging: Moisture-proof containers with clear hazard labeling

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific OSHA or ACGIH limits established; follow standard nuisance dust limits (e.g., 10 mg/m³ total, 5 mg/m³ respirable)
Engineering Controls: Use fume hood, local exhaust, or HEPA-filtered ventilation for dusty processes
Personal Protective Equipment: Nitrile gloves, chemical splash goggles, dust respirator for heavy dust, lab coat
Hygiene Measures: Wash hands and arms thoroughly after handling, remove contaminated clothing, avoid eating or drinking near material

Physical and Chemical Properties

Appearance: White or off-white powder
Odor: No significant smell
pH (suspension): 2–3 in water
Melting Point: Decomposes before melting
Boiling Point: Not applicable (solid, decomposes on high heat)
Solubility: Insoluble in water, reacts with strong bases
Specific Gravity: 2.2–2.5
Vapor Pressure: Not relevant
Particle Size: Typically fine powder, size varies by batch
Other: Moisture content may vary if stored open

Stability and Reactivity

Chemical Stability: Keeps form at room temperature under dry conditions
Possible Reactions: Reacts with strong alkalis, attacks metals if in acidic solution
Hazardous Decomposition: Forms phosphorus oxides and possibly zirconium oxides at high temperature
Conditions to Avoid: Strong heat, high humidity, acids, alkalis, sources of ignition
Incompatible Materials: Alkalis, metal powders, strong acids for extended exposure

Toxicological Information

Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: May cause mild irritation to eyes, skin, throat on contact with dust
Chronic Effects: No evidence of carcinogenicity, mutagenicity, or reproductive toxicity in animals
LD50/LC50 Data: No data available; low toxicity expected based on structure and analogs
Signs of Overexposure: Coughing, sneezing, rashes, irritation if dust is breathed or contacts skin and eyes
Other Health Effects: No reports of long-term health effects from occupational exposure under controlled handling

Ecological Information

Toxicity to Aquatic Life: Low toxicity expected; insoluble solid unlikely to bioaccumulate
Mobility: Sinks in water, binds to soil particles, unlikely to reach groundwater
Persistence/Degradability: Not biodegradable, remains in natural state for long periods
Bioaccumulation Potential: Does not bioaccumulate
Other Environmental Hazards: Excessive dust or spills could alter soil pH or texture if released in large amounts

Disposal Considerations

Waste Treatment Methods: Collect into suitable container for approved disposal
Disposal Guidelines: Follow local, state, and federal regulations for solids, consult waste management authority
Disposal of Container: Rinse empty packaging thoroughly before discarding or recycling
Incineration Notes: Not suitable for incinerators due to mineral nature and release of minor phosphorus oxides on extreme heat

Transport Information

UN Number: Not classified under transport regulations
Transport Hazard Class: Not listed as dangerous good
Packing Group: Not applicable
Special Precautions: Avoid container damage or mixing with reactive cargo, keep sealed
Transport Labels: No special labeling required unless state or country specifies otherwise
Shipping Name: Zirconium hydrogen phosphate, solid

Regulatory Information
