The mechanism by which chemistry and engineering helped transform aluminum from a precious metal into an inexpensive structural material.
Concept Introduction: If the isolation and extraction of the material is tedious, time consuming, labor intensive with low yield then the material will be expensive. Also since the yield is low it will be considered as a precious metal.
Charles Hall developed a cheaper and more efficient method to extract aluminum from bauxite.
Charles Hall developed a method for extracting aluminum from bauxite that was cheaper and more efficient. His method also reduced the energy input needed to extract aluminum. So with the lowering cost of hydroelectricity, the availability of aluminum increased greatly. The fields of chemistry and engineering are always evolving to develop new methods of metal extraction.
The mechanism by which chemistry and engineering helped transform aluminum from a precious metal into an inexpensive structural material was discussed.
