Questions & Answers

Q: Why was aluminum more valuable than gold at one point?

Aluminum was difficult to obtain in its pure metallic form, and its scarcity, coupled with high demand, drove up its price.

Q: How did the discovery of aluminum production techniques impact its price?

The development of the Héroult/Hall process and the cheap production of aluminum oxide from bauxite significantly reduced the price of aluminum.

Q: What practical applications did aluminum have historically?

Aluminum was initially considered a curiosity and used for jewelry. Emperor Napoleon III hoped to use it for lightweight weapons and armor, but the cost hindered this plan.

Q: How did aluminum go from being rare to common?

The discovery of electrolysis by Paul Lois Toussaint Héroult and Charles Martin Hall, along with the cheap production of aluminum oxide, led to a mass production of aluminum and a drastic drop in its price.

Summary & Key Takeaways

  • Aluminum, a common element, exists mainly as a chemical compound rather than in metallic form.

  • Chemical compounds containing aluminum are referred to as "alum," but not all alums contain aluminum.

  • The discovery and production of aluminum as a metal took several years, with breakthroughs in isolating and producing it in larger quantities.
