Yes, aluminum melts at a higher temperature than its oxide, aluminum oxide (Al2O3).

Here's why:

* Aluminum's melting point: 660.32 °C (1220.58 °F)

* Aluminum oxide's melting point: 2072 °C (3762 °F)

Aluminum oxide is a very stable compound with strong ionic bonds. These bonds require a lot of energy to break, which explains its much higher melting point compared to pure aluminum.
