Properties & Characteristics

Appearance: bluish-white, lustrous metal. Melting point: 419.53 °C. Boiling point: 907 °C. Density: 7.13 g/cm³. Hardness: 2.5 Mohs (brittle at room temperature).

Uses & Applications

Galvanising steel (largest use — prevents corrosion). Zinc alloys (brass, die-casting alloys). Zinc oxide in rubber, paints, sunscreen, and pharmaceuticals. Dietary supplement (essential micronutrient). Dry-cell batteries (zinc-carbon, alkaline).

Safety Information

Essential micronutrient; deficiency causes immune dysfunction. Zinc oxide fume causes metal fume fever. High doses toxic; disrupts copper absorption. Zinc chloride and other soluble salts are irritants.
