What is the boiling point of sapphire?

Sapphire, primarily composed of aluminum oxide (Al2O3), does not have a defined boiling point like liquids do, as it is a solid ceramic material. However, it can be thermally decomposed at extremely high temperatures, typically above 2000°C (3632°F). In practical applications, sapphire is often used in high-temperature environments due to its stability and resistance to thermal shock.
