Before the Hall Process, it was hard to obtain aluminum, which was a problem because aluminum is a very useful metal. The Hall Process made it much easier to produce aluminum, so after its creation, aluminum began to be commercially produced. In the process, aluminum oxide is dissolved in molten cryolite, and then electrolyzed. Dissolving it in the cryolite first makes it a lot easier to electrolyze the oxide into aluminum and oxygen.
The formula: 2Al2O3 -> 4Al + 3O2
The Hall Process made low-priced aluminum available for the first time, contributing to its global use today. However, carbon anodes are involved in this process, and their production involve carbon compounds that contribute to greenhouse gas emissions, which is bad for the environment.
