  1. Electrolytic Production of Aluminum ---- Vicky Hou Ivy Zhang

  2. The Properties and Uses of Aluminum • It had being called “silver gold” in hundred years ago • Aluminum is very reactive • There’s no natural pure aluminum metal • The MP is 660℃ • The BP is 2500℃ • The density is 2.7g/cm3 • Aluminum can be used in many kinds of industries.

  3. Aluminum is the most widely used metal. • Global production of aluminum in 2005 was 31.9 million tones • Aluminum is almost alloyed, which markedly improves its mechanical properties. • The main alloying agents are copper(Cu), zinc(Zn), magnesium(Mg), manganese(Mn), and silicon(Si).

  4. Since aluminum is very reactive, when aluminum foil stays in the atmosphere, it will react with oxygen and produce a thin Al2O3 film on surface of the foil. • In China, 113 out of 124 kinds of industries using the products of aluminum.

  5. Major Uses of Aluminum • Transportation • Packaging (cans, foil, etc.) • Construction (windows, doors, siding, building wire, etc.). • A wide range of household items, from cooking utensils to baseball bats, watches. • Street lighting poles, sailing ship masts, walking poles, etc. • Outer shells of consumer electronics, also cases for equipment e.g. photographic equipment. • Electrical transmission lines for power distribution

  6. What is Electrolytic Production of Aluminum • It is a way that industry used to produce pure aluminum metal. • It start with the impure aluminum oxide “bauxite”.

  7. Basic Materials • Alumina • Flux +Cryolite • Alumina has melting point at 2045℃ • The flux and cryolite are added in order to lower the melting point of the alumina

  8. Chemical Reactions • Total Reaction: • Cathode: Anode:
