In the natural world, you won’t find aluminum in its pure form because it is always combined with other elements in compounds like bauxite. When we refine aluminum industrially, we still can’t achieve 100% purity because there are tiny impurities present. Although we can obtain high purity aluminum, like 99.99%, it’s still not completely pure. Even with advanced methods like zone melting, we can’t reach absolute purity because of the laws of thermodynamics and kinetics.
