TUNGSTEN OXIDE (WO3) MATERIAL SAFETY DATA SHEET (MSDS/SDS) KEY POINTS
(tungsten oxide msds)
**PRODUCT IDENTIFICATION:** Chemical Name: Tungsten(VI) Oxide. Synonyms: Tungstic anhydride, Tungsten trioxide. Formula: WO3. CAS No.: 1314-35-8. Common Uses: Ceramics, catalysts, coatings, electronics, gas sensors.
**HAZARDS IDENTIFICATION:** Generally considered low hazard. Low acute toxicity. May cause mechanical irritation to eyes, skin, or respiratory tract. Dust may cause coughing or sneezing. Not classified as flammable or explosive under normal conditions. Chronic inhalation of high dust levels may potentially cause lung effects (pneumoconiosis), but low likelihood with typical handling.
**HANDLING & STORAGE:** Handle to minimize dust generation. Avoid breathing dust. Use adequate ventilation, especially in enclosed spaces. Local exhaust ventilation recommended for significant dust generation. Store in a cool, dry, well-ventilated place. Keep container tightly closed. Store away from incompatible materials like strong reducing agents. Stable under recommended conditions.
**EXPOSURE CONTROLS / PERSONAL PROTECTION:** Engineering Controls: Use local exhaust ventilation. General room ventilation usually sufficient for small amounts. Personal Protective Equipment (PPE): Safety glasses with side shields. Consider chemical goggles if significant dust splash risk. Wear gloves (nitrile, neoprene suggested). Wear protective clothing to prevent skin contact. Use dust respirator (NIOSH N95 or equivalent) if ventilation is inadequate and exposure limits are exceeded or dust is bothersome.
**PHYSICAL & CHEMICAL PROPERTIES:** Appearance: Yellow crystalline powder or chunks. Odor: Odorless. Solubility: Insoluble in water, slightly soluble in alkaline solutions. Melting Point: ~1473°C (2683°F). Density: ~7.2 g/cm³.
**STABILITY & REACTIVITY:** Stable under normal conditions. Incompatible with strong reducing agents, strong acids, active metals (e.g., aluminum, magnesium). May react vigorously. No hazardous decomposition under normal use.
**FIRST AID MEASURES:** Eyes: Flush immediately with plenty of water for at least 15 minutes. Seek medical attention if irritation persists. Skin: Wash off with soap and plenty of water. Inhalation: Move to fresh air. If breathing is difficult, seek medical attention. Ingestion: Rinse mouth. Do NOT induce vomiting. Seek medical advice.
**SPILLS:** Wear appropriate PPE. Avoid raising dust. Sweep up or vacuum carefully using equipment with HEPA filtration. Place in suitable container for disposal. Prevent material from entering drains or waterways.
**DISPOSAL:** Dispose of waste material according to all applicable local, regional, national (e.g., RCRA), and international regulations. Consult authorities.
