  2. Industrial use • Medical use • Biological Use

  3. Industrial Use 1) An anti-corrosion agent (most commonly) • Galvanization(55%) • Used on … ... chain-link fencing guard rails suspension bridges lightposts metal roofs heat exchangersHot-dip handrail galvanized crystalline surface car bodies

  4. Industrial Use 2) An efficient sacrificial anode in cathodic protection • Acts as the anode • Protect metals that are exposed to sea water from corrosion iron T-Bolt without/with cathodic protection

  5. Industrial Use 3) Alloy (Brass) • More ductile and stronger • Superior corrosion resistance • Useful in … … communication equipment hardware musical instruments  water valves Cast brass microstructure at magnification 400x

  6. Industrial Use 4) Zinc-air batteries • Electro-chemical batteries • High energy densities • Relatively inexpensive to produce • Useful in … … electric vehicle propulsion Zinc -air button cell film camera

  7. Medical Use 1) Dietary supplement • Single tablet over-the-counter daily vitamin & mineral supplements • Protect against … … accelerated aging of the skin muscles of the body • Speed up the healing process

  8. Medical Use 2) Cure diseases • Effective treatment for … … Age-related macular degeneration(老年黃斑點病變) Acrodermatitis enteropathica • Protect against … … Diaper rash(尿布疹) Sunburn & Windburn

  9. Biological Use 1) Enzyme • A useful catalytic agent • Necessary for … ... plants animals microorganisms • Coordinate to the amino acid side chains of … … aspartic acid glutamic acid cysteine and histidine.

  10. Biological Use 2) In human body • 2–4 grams distributing throughout the human body brainmuscle boneskidney liverprostate parts of the eye.
